general description the max15008 features a 300ma ldo regulator, a volt- age tracker, and an overvoltage protection (ovp) con- troller to protect downstream circuits from high-voltage load dump. the MAX15010 includes only the 300ma ldo voltage regulator and voltage tracker. both devices operate over a wide 5v to 40v supply voltage range and are able to withstand load-dump transients up to 45v. the max15008/MAX15010 feature short-circuit and thermal- shutdown protection. these devices offer highly integrat- ed power-management solutions for automotive applications such as instrument clusters, climate control, and a variety of automotive power-supply circuits. the 300ma ldo regulator consumes less than 70? qui- escent current at light loads and is well suited to power always-on circuits during ?ey off?conditions. the ldo features independent enable and hold inputs as well as a microprocessor (?) reset output with an adjustable reset timeout period. the voltage tracker accurately (?mv) tracks a voltage applied to its input from either the ldo output or an exter- nal source. it can supply up to 50ma of current to a remote sensor, allowing for precise ratiometric tracking in automotive applications. a separate enable input turns the tracker on or off, reducing supply current when the tracker is unused. the voltage tracker also features pro- tection against battery reversal, an output short circuit to the battery, or an output-voltage excursion below ground potential to as much as -5v. the max15008 ovp controller operates with an external enhancement mode n-channel mosfet. while the moni- tored voltage remains below the adjustable threshold, the mosfet stays on. when the monitored voltage exceeds the ovp threshold, the ovp controller quickly turns off the external mosfet. the ovp controller is configurable as a load-disconnect switch or a voltage limiter. the max15008/MAX15010 are available in a thermally enhanced, 32-pin (5mm x 5mm) tqfn package and are fully specified over the -40? to +125? automotive oper- ating temperature range. applications instrument clusters climate control am/fm radio power supply multimedia power supply telematics power supply features ? 300ma ldo regulator, voltage tracker, and ovp controller (max15008) ? 300ma ldo regulator and voltage tracker (MAX15010) ? 50ma voltage tracker with ?mv tracking accuracy ? 5v to 40v wide operating supply voltage range ? 45v load dump protection ? 70? quiescent current ldo regulator ? ovp controller disconnects or limits output from battery overvoltage conditions (max15008) ? ldo regulator with enable, hold, and reset features max15008/MAX15010 automotive 300ma ldo voltage regulators with tracker output and overvoltage protector ________________________________________________________________ maxim integrated products 1 max15008 tqfn (5mm x 5mm) + top view 29 30 28 27 12 11 13 n.c. adj sgnd pgnd reset 14 n.c. n.c. out_ldo in n.c. in en_prot 12 n.c. 4567 23 24 22 20 19 18 fb_trk track ref source gate n.c. out_trk out_ldo 3 21 31 10 n.c. fb_prot 32 9 n.c. ct n.c. 26 15 fb_ldo *ep *ep = exposed pad n.c. 25 16 en_ldo n.c. en_trk 8 17 hold pin configurations 19-0996; rev 0; 9/07 for pricing, delivery, and ordering information, please contact maxim direct at 1-888-629-4642, or visit maxim? website at www.maxim-ic.com. typical operating circuits appear at end of data sheet. pin configurations continued at end of data sheet. ordering information + denotes a lead-free package. * future product?ontact factory for availability. ** ep = exposed pad. part ldo tracker ovp controller max15008 ?

detailed description the max15008/MAX15010 integrate a 300ma ldo voltage regulator, a voltage tracker, and an ovp con- troller. these devices operate over a wide 5v to 40v supply voltage range and are able to withstand load- dump transients up to 45v. the max15008/MAX15010 feature a 300ma ldo regu- lator that consumes less than 70? of current under light-load conditions and feature a fixed 5v or an adjustable output voltage (1.8v to 11v). connect fb_ldo to ground to select a fixed 5v output voltage or select the ldo output voltage by connecting an external resistive voltage-divider at fb_ldo. the regu- lator sources at least 300ma of current and includes a current limit of 330ma (min). enable the ldo by pulling en_ldo high. the tracker can be powered from the ldo input sup- ply voltage or an independent voltage source. it is designed to supply power to a remote sensor and is able to handle the severe conditions in automotive applications. set the tracker output voltage by con- necting a resistive voltage-divider to out_trk and connecting adj to the tracking source. the tracker feedback, fb_trk, and a separate tracker reference voltage input, adj, offer the flexibility of setting the tracker output to be lower, equal to, or higher than the main (ldo) output. pull en_trk to sgnd to turn the tracker off and keep the device in always-on, low- quiescent-current operation. the ovp controller (max15008 only) relies on an exter- nal mosfet with adequate voltage rating (v dss ) to protect downstream circuitry from overvoltage tran- sients. the ovp controller drives the gate of the exter- nal n-channel mosfet, and is configurable to operate as an overvoltage protection switch or as a closed-loop voltage limiter. gate voltage (max15008 only) the max15008 uses a high-efficiency charge pump to generate the gate voltage for the external n-channel mosfet. once the input voltage, v in , exceeds the undervoltage lockout (uvlo) threshold, the internal charge pump fully enhances the external n-channel mosfet. an overvoltage condition occurs when the voltage at fb_prot goes above the threshold voltage, v th_prot . after v th_prot is exceeded, gate is quick- ly pulled to pgnd with a 63ma pulldown current. the max15008 includes an internal clamp from gate to source that ensures that the voltage at gate never exceeds one diode drop below source during gate discharge. the voltage clamp also prevents the gate- to-source voltage from exceeding the absolute maxi- mum rating for the v gs of the external mosfet in case the source terminal is accidentally shorted to 0v. overvoltage monitoring (max15008 only) the ovp controller monitors the voltage at fb_prot and controls an external n-channel mosfet, isolating, or limiting the load during an overvoltage condition. operation in ovp switch mode or limiter mode depends on the connection between fb_prot and the external mosfet. overvoltage switch mode when operating in ovp switch mode, the fb_prot divider is connected to the drain of the external mosfet. the feedback path consists of the voltage- divider tapped at fb_prot, fb_prot? internal comparator, the internal gate charge pump/gate pulldown, and the external n-channel mosfet (figure 1). when the programmed overvoltage threshold is exceeded, the internal comparator quickly pulls gate to ground and turns off the external mosfet, disconnecting the power source from the load. in this configuration, the voltage at the source of the mosfet is not monitored. when the voltage at fb_prot decreases below the overvoltage threshold, the max15008 raises the voltage at gate, reconnecting the load to the power source. max15008/MAX15010 automotive 300ma ldo voltage regulators with tracker output and overvoltage protector ______________________________________________________________________________________ 13 in v in fb_prot sgnd gate source protector output max15008 figure 1. overvoltage switch configuration (max15008)
max15008/MAX15010 automotive 300ma ldo voltage regulators with tracker output and overvoltage protector 14 ______________________________________________________________________________________ overvoltage-limiter mode when operating in overvoltage-limiter mode, the feed- back path consists of source, fb_prot? internal comparator, the internal gate charge pump/gate pull- down, and the external n-channel mosfet (figure 2). this configuration results in the external mosfet oper- ating as a hysteretic voltage regulator. during normal operation, gate is enhanced 8.1v above v in . the external mosfet source voltage is monitored through a resistive voltage-divider between source and fb_prot. when v source exceeds the adjustable overvoltage threshold, an internal pulldown switch discharges the gate voltage and quickly turns the mosfet off. consequently, the source voltage begins to fall. the v source fall time is dependent on the mosfet? gate charge, the internal charge-pump current, the output load, and any load capacitance at source. when the voltage at fb_prot is below the overvoltage threshold by an amount equal to the hys- teresis, the charge pump restarts and turns the mosfet back on. in this way, the ovp controller attempts to regulate v source around the overvoltage threshold. source remains high during overvoltage transients and the mosfet continues to conduct dur- ing an overvoltage event. the hysteresis of the fb_prot comparator and the gate turn-on delay force the external mosfet to operate in a switched on/off sequence during an overvoltage event. exercise caution when operating the max15008 in voltage-limiting mode for long durations. care must be taken against prolonged or repeated exposure to overvoltage events while delivering large amounts of load current as the power dissipation in the external mosfet may be high under these conditions. to pre- vent damage to the mosfet, implement proper heatsinking. the capacitor connected between source and ground can also be damaged if the rip- ple current rating for the capacitor is exceeded. as the transient voltage decreases, the voltage at source falls. for fast-rising transients and very large mosfets, connect an additional capacitor from gate to pgnd. this capacitor acts as a voltage-divider work- ing against the mosfet? drain-to-gate capacitance. if using a very low gate charge mosfet, additional capacitance from gate to ground might be required to reduce the switching frequency. control logic the max15008/MAX15010 ldo features two logic inputs, en_ldo and hold , making these devices suit- able for automotive applications. for example, when the ignition key signal drives en_ldo high, the regula- tor turns on and remains on even if en_ldo goes low, as long as hold is forced low and stays low after initial regulator power-up. in this state, releasing hold turns the regulator output (out_ldo) off. this feature makes it possible to implement a self-holding circuit without external components. forcing en_ldo low and hold high (or unconnected) places the regulator into shut- down mode reducing the supply current to less than 16?. table 1 shows the state of out_ldo with respect to en_ldo and hold . leave hold uncon- nected or connect directly to out_ldo to allow the en_ldo input to act as a standard on/off logic input for the regulator. in v in fb_prot sgnd gate source protector output max15008 figure 2. overvoltage limiter (max15008)
applications information load dump most automotive applications run off a multicell 12v lead-acid battery with a nominal voltage that swings between 9v and 16v, depending on load current, charging status, temperature, and battery age, etc. the battery voltage is distributed throughout the automobile and is locally regulated down to voltages required by the different system modules. load dump occurs when the alternator is charging the battery and the battery becomes disconnected. power in the alternator (behav- ing now essentially as an inductor) flows into the dis- tributed power system and elevates the voltage seen at each module. the voltage spikes have rise times typi- cally greater than 5ms and decay within several hun- dred milliseconds but can extend out to 1s or more depending on the characteristics of the charging sys- tem. these transients are capable of destroying semi- conductors on the first fault event. the max15008/MAX15010 feature load-dump transient protection up to +45v. setting the output voltage the max15008/MAX15010 feature dual-mode opera- tion: these devices operate in either a preset voltage mode or an adjustable mode. in preset voltage mode, internal feedback resistors set the linear regulator out- put voltage (v out_ldo ) to 5v. to select the preset 5v output voltage, connect fb_ldo to sgnd. to select an adjustable output voltage between 1.8v and 11v, use two external resistors connected as a voltage-divider to fb_ldo (figure 3). set the output voltage using the following equation: v out_ldo = v fb_ldo x (r 1 + r 2 ) / r 2 where v fb_ldo = 1.235v and r 2 50k . max15008/MAX15010 automotive 300ma ldo voltage regulators with tracker output and overvoltage protector ______________________________________________________________________________________ 15 in r1 r2 v in fb_ldo sgnd out_ldo max15008 MAX15010 figure 3. setting the ldo output voltage table 1. en_ldo/ h h o o l l d d truth table/state table operation state en_ldo hold out_ldo comment initial state low don? care off en_ldo is pulled to sgnd through an internal pulldown. hold is unconnected and is internally pulled up to out_ldo. the regulator is disabled. turn-on state high don? care on en_ldo is externally driven high turning regulator on. hold is pulled up to out_ldo. hold setup state high low on hold is externally pulled low while en_ldo remains high (latches en_ldo state). hold state low low on en_ldo is driven low or left unconnected. hold remains externally pulled low keeping the regulator on. off state low high or unconnected off hold is driven high or left unconnected while en_ldo is low. the regulator is turned off and en_ldo/ hold logic returns to the initial state.
max15008/MAX15010 setting the reset timeout period the reset timeout period is adjustable to accommodate a variety of applications. set the reset timeout period by connecting a capacitor, c reset , between ct and sgnd. use the following formula to select the reset timeout period, t reset : t reset = c reset x v ct_th / i ct where t reset is in seconds and c reset is in ?. v ct_th is the ct ramp threshold in volts and i ct is the ct ramp current in ?, as described in the electrical characteristics table. leave ct open to select an internally fixed timeout peri- od of 10?. to maintain reset timeout accuracy, use a low-leakage (< 10na) type capacitor. tracker input/feedback adjustment the tracker can be powered from the ldo input supply voltage or an independent voltage source. it is designed to supply power to a remote sensor and its supply input, track, is able to handle the severe con- ditions in automotive applications such as battery reversal and load-dump transients up to 45v. the tracker feedback, fb_trk, and a separate tracker reference voltage input, adj, offer the flexibility of set- ting the tracker output to be lower, equal to, or higher than the main (ldo) output. other external voltages can also be tracked. connect adj to out_ldo and fb_trk to out_trk to track the ldo output voltage directly (figure 4a). to track a voltage higher than v out_ldo , directly connect adj to out_ldo and connect fb_trk to out_trk through a resistive voltage-divider (figure 4b). to track a voltage lower than the ldo regulator output, v out_ldo , directly connect fb_trk to out_trk and connect adj to out_ldo through a resistive voltage- divider (figure 4c). to track an external voltage v x with a generic attenuation/amplification ratio, connect resis- tive voltage-dividers between adj and the voltage input or output to be tracked (v x ), and between out_trk and fb_trk (figure 4d). pay attention to the resistive loading of the voltage v x due to the divider r5, r6. to track the internal ref voltage (1.235v), directly connect adj to ref. the voltage at fb_trk or adj should be greater than or equal to 1.1v and less than v track - 0.5v. resistors should have a tolerance of 1% or better. their values should be low enough to ensure that the divider current is at least 100x the maximum input bias current at pins fb_trk and adj (i fb_trk_adj , max = 0.2?). automotive 300ma ldo voltage regulators with tracker output and overvoltage protector 16 ______________________________________________________________________________________ in ldo output v in out_trk out_ldo tracker output fb_trk adj max15008 MAX15010 track in ldo output r3 v in out_trk out_ldo tracker output adj max15008 MAX15010 r4 fb_trk r5 r6 r6 track to track v out_ldo : v out_trk = v out_ldo to track a voltage higher than v out_ldo : v out_trk = v out_ldo x (r3 + r4) / r4, r3 + r4 < v out_trk / 20 a (a) (b) in ldo output v in out_trk out_ldo tracker output fb_trk adj max15008 MAX15010 track in r3 v in out_trk adj tracker output max15008 MAX15010 r4 fb_trk track to track a voltage lower than v out_ldo : v out_trk = v out_ldo x r6 / (r5 + r6), r5 + r6 < v out_ldo / 20 a to track a generic voltage v x : v out_trk = v x x (r6 / (r5 + r6)) x ((r3 + r4) / r4), r5 + r6 < v x / 20 a, r3 + r4 < v out_trk / 20 a r5 (c) (d) v x figure 4. tracker input and feedback adjustment
setting the overvoltage threshold (max15008 only) the max15008 provides an accurate means to set the overvoltage threshold for the ovp controller using fb_prot. use a resistive voltage-divider to set the desired overvoltage threshold (figure 5). fb_prot has a rising 1.235v threshold with a 4% falling hysteresis. begin by selecting the total end-to-end resistance, r total = r 5 + r 6 . choose r total to yield a total cur- rent equivalent to a minimum of 100 x i fb_prot (fb_prot? input maximum bias current) at the desired overvoltage threshold. see the electrical characteristics table. for example: with an overvoltage threshold (v ov ) set to 20v, r total < 20v / (100 x i fb_prot ), where i fb_prot is fb_prot? maximum 100na bias current: r total < 2m use the following formula to calculate r 6 : r 6 = v th_prot x r total / v ov where v th_prot is the 1.235v fb_prot rising thresh- old and v ov is the desired overvoltage threshold. r 6 = 124k : r total = r 5 + r 6 where r 5 = 1.88m . use a standard 1.87m resistor. a lower value for total resistance dissipates more power, but provides better accuracy and robustness against external disturbances. input transients clamping when the external mosfet is turned off during an overvoltage event, stray inductance in the power path may cause additional input-voltage spikes that exceed the v dss rating of the external mosfet or the absolute maximum rating for the max15008 (in, track). minimize stray inductance in the power path using wide traces and minimize the loop area included by the power traces and the return ground path. for further protection, add a zener diode or transient voltage suppressor (tvs) rated below the absolute maximum rating limits (figure 6). max15008/MAX15010 automotive 300ma ldo voltage regulators with tracker output and overvoltage protector ______________________________________________________________________________________ 17 r6 r5 r5 r6 in v in fb_prot sgnd gate source protector output max15008 in v in fb_prot sgnd gate source protector output max15008 figure 5. setting the overvoltage threshold (max15008) in v in sgnd gate source tvs max15008 load figure 6. protecting the max15008 input from high-voltage transients
max15008/MAX15010 external mosfet selection select the external mosfet with adequate voltage rating, v dss , to withstand the maximum expected load- dump input voltage. the on-resistance of the mosfet, r ds(on) , should be low enough to maintain a minimal voltage drop at full load, limiting the power dissipation of the mosfet. during regular operation, the power dissipated by the mosfet is: p normal = i load 2 x r ds(on) normally, this power loss is small and is safely handled by the mosfet. however, when operating the max15008 in overvoltage-limiter mode under pro- longed or frequent overvoltage events, select an exter- nal mosfet with an appropriate power rating. during an overvoltage event, the power dissipation in the external mosfet is proportional to both load cur- rent and to the drain-source voltage, resulting in high power dissipated in the mosfet (figure 7). the power dissipated across the mosfet is: p ov_limiter = v q1 x i load where v q1 is the voltage across the mosfet? drain and source during overvoltage-limiter operation, and i load is the load current. overvoltage-limiter mode switching frequency when the max15008 is configured in overvoltage- limiter mode, the external n-channel mosfet is subse- quently switched on and off during an overvoltage event. the output voltage at source resembles a periodic sawtooth waveform. calculate the period of the waveform, t ovp , by summing three time intervals (figure 8): t ovp = t 1 + t 2 + t 3 where t 1 is the v source output discharge time, t 2 is the gate delay time, and t 3 is the v source output charge time. during an overvoltage event, the power dissipated inside the max15008 is due to the gate pulldown cur- rent, i gatepd . this amount of power dissipation is worse when i source = 0 (c source is discharged only by the internal current sink). the worst-case internal power dissipation contribution in overvoltage-limiter mode, p ovp , in watts can be approximated using the following equation: where v ov is the overvoltage threshold voltage in volts and i gatepd is the 63ma (typ) gate pulldown current. output discharge time (t 1 ) when the voltage at source exceeds the adjusted overvoltage threshold, gate? internal pulldown is enabled until v source drops by 4%. the internal cur- rent sink, i gatepd , and the external load current, i load , discharge the external capacitance from source to ground. pv i t t ovp ov gatepd ovp = 098 1 . automotive 300ma ldo voltage regulators with tracker output and overvoltage protector 18 ______________________________________________________________________________________ t 2 t 1 t ovp t 3 gate source figure 8. max15008 timing diagram in fb_prot sgnd gate source tvs max15008 load i load + v q1 - v source v source v ov v max figure 7. power dissipated across mosfets during an overvoltage fault (overvoltage limiter mode)
calculate the discharge time, t 1 , using the following equation: where t 1 is in ms, v ov is the adjusted overvoltage threshold in volts, i load is the external load current in ma, and i gatepd is the 63ma (typ) internal pulldown current of gate. c source is the value of the capacitor connected between the source of the mosfet and pgnd in ?. gate delay time (t 2 ) when source falls 4% below the overvoltage threshold voltage, the internal current sink is disabled and the internal charge pump begins recharging the external gate voltage. due to the external load, the source voltage continues to drop until the gate of the mosfet is recharged. the time needed to recharge gate and re- enhance the external mosfet is approximately: where t 2 is in ?, c iss is the input capacitance of the mosfet in pf, and v gs(th) is the gate-to-source thresh- old voltage of the mosfet in volts. v f is the 0.7v (typ) internal clamp diode forward voltage of the mosfet in volts, and i gate is the charge-pump current 45? (typ). any external capacitance between gate and pgnd will add up to c iss . during t 2 , the source capacitance, c source , loses charge through the output load. the voltage across c source , v 2 , decreases by v 2 until the mosfet reaches its v gs(th) threshold. approximate v 2 using the following formula: source output charge time (t 3 ) once the gate voltage exceeds the gate-to-source thresh- old, v gs(th) , of the external mosfet, the mosfet turns on and the charge through the internal charge pump with respect to the drain potential, q g , determines the slope of the output-voltage rise. the time required for the source voltage to rise again to the overvoltage threshold is: where v source = (v ov x 0.04) + v 2 in volts, and c rss is the mosfet? reverse transfer capacitance in pf. any external capacitance between gate and pgnd adds up to c rss . power dissipation/junction temperature during normal operation, the max15008/MAX15010 has two main sources of internal power dissipation: the ldo and the voltage tracker. calculate the power dissipation due to the ldo as: p ldo = (v in - v out_ldo ) x i out_ldo where v in is the ldo input supply voltage in volts, v out_ldo is the output voltage of the ldo in volts, and i out_ldo is the ldo total load current in ma. calculate power dissipation due to the tracker as: p trk = (v track - v out_trk ) x i out_trk where v track is the tracker input supply voltage in volts, v out_trk is the output voltage of the tracker in volts, and i out_trk is the tracker load current in ma. the total power dissipation p diss in mw as: p diss = p ldo + p trk for prolonged exposure to overvoltage events, use the v in and v track voltages expected during overvoltage conditions. under these circumstances the corre- sponding internal power dissipation contribution, p ovp , calculated in the overvoltage-limiter mode switching frequency section should also be included in the total power dissipation, p diss . for a given ambient temperature, t a , calculate the junction temperature, t j , as follows: t j = t a + p diss x ja where t j and t a are in ? and ja is the junction-to- ambient thermal resistance in ?/w as listed in the absolute maximum ratings section. the junction temperature should never exceed +150? during normal operation. thermal protection when the junction temperature exceeds t j = +160?, the max15008/MAX15010 shut down to allow the device to cool. when the junction temperature drops to +140?, the thermal sensor turns all enabled blocks on again, resulting in a cycled output during continu- ous thermal-overload conditions. thermal protection protects the max15008/MAX15010 from excessive power dissipation. for continuous operation, do not exceed the absolute maximum junction temperature rating of +150?. t cv i rss source gate 3 = v it c load source 2 2 = tc vv i iss gs th f gate 2 = + () tc 0.04 v ii 1 source ov load gatepd = + max15008/MAX15010 automotive 300ma ldo voltage regulators with tracker output and overvoltage protector ______________________________________________________________________________________ 19
