general description the max5023/max5024 high-voltage linear regulators operate from a +6.5v to +65v input voltage and deliver up to 150ma of output current. these devices consume only 60? of quiescent current with no load and with- stand a -60v reverse-battery voltage at the input. the max5023/max5024 include an active-low internal microprocessor (?) reset circuit that asserts when the regulator output drops below the preset output voltage threshold by 7.5% or 12.5%, depending on the device selected. both devices are available with a fixed +3.3v or +5v output. these devices are short-circuit protected and include thermal shutdown. in addition to an enable input to turn on or off the regu- lator, the max5023/max5024 include a hold input that allows for the implementation of a self-holding circuit without requiring external components. setting hold low after enabling the regulator, forces the regu- lator to remain on even if en is subsequently set low. releasing hold shuts down the regulator. the max5023 includes a watchdog input that monitors a pulse train from the ? and generates reset pulses if the watchdog input remains high or low for a duration longer than the 1.6s watchdog timeout period. the max5024 includes a set input which, when connected to ground, selects a preset output voltage of +3.3v (max5024s/ max5024t) or +5v (max5024l/max5024m). set the adjustable output voltage by connecting set to the regu- lator? output through a resistive-divider network. the max5023/max5024 operate over the automotive temperature range (-40? to +125?) and are available in a thermally enhanced, surface-mount 8-pin so-ep package. applications automotive fire/smoke alarms industrial telecom/networking home security features ? wide operating input voltage range +6.5v to +65v ? thermally enhanced 8-pin so package with exposed pad dissipates 1.5w ? guaranteed 150ma output current ? 60a no-load supply current ? -60v reverse-battery protection ? preset +3.3v or +5.0v output voltage ? thermal and short-circuit protection ? operate over -40c to +125c temperature range ? integrated p reset circuit ? watchdog timer with 1.6s timeout period (max5023) ? regulator enable and hold inputs implement self-holding circuit ? set input for adjustable output voltage (max5024) max5023/max5024 65v, low-quiescent-current, high-voltage linear regulators with p reset and watchdog timer ________________________________________________________________ maxim integrated products 1 n.c. hold reset 1 2 8 7 out wdi en gnd in so-ep top view 3 4 6 5 max5023 n.c. hold reset 1 2 8 7 out set en gnd in so-ep 3 4 6 5 max5024 part temp range pin-package max5023 _ asa -40? to +125? 8 so-ep* max5024 _ asa -40? to +125? 8 so-ep* pin configurations ordering information 19-2619; rev 1; 2/04 for pricing, delivery, and ordering information, please contact maxim/dallas direct! at 1-888-629-4642, or visit maxim? website at www.maxim-ic.com. selector guide and typical operating circuit appear at end of data sheet. note: these parts offer a choice of reset thresholds, reset threshold tolerances, and regulator output voltages. from the selector guide, insert the desired suffix letter into the blank to complete the part number. * ep = exposed paddle.

detailed description the max5023/max5024 high-voltage linear regulators include an integrated ? reset circuit and watchdog timer/adjustable output voltage. the devices guarantee 150ma load drive and are available with preset output voltages of +3.3v or +5v. the max5023 features a watchdog timer (wdi) with a 1.6s timeout period. the max5024 offers an adjustable output voltage using an external resistive-divider network between set and out. the internal reset circuit monitors the regulator output voltage and asserts a reset output when the reg- ulator output falls below the ? supply tolerance. other features include reverse-voltage protection to -60v, enable (en) and hold ( hold ) regulator control inputs, 16? (max) shutdown current, short-circuit protection, and thermal shutdown. regulator the regulator accepts an input voltage range from +6.5v to +65v. the max5023/max5024 offer fixed out- put voltages of +3.3v and +5v. the max5024 also fea- tures an adjustable output voltage that is implemented with an external resistive-divider network connected between out, set, and gnd (figure 1). the max5024 automatically determines the feedback path depending on the voltage at set. featured characteristics include reverse-voltage protection to -60v and enable and hold regulator control inputs. the typical operating circuit shows a self-holding configuration for the max5023. max5023/max5024 65v, low-quiescent-current, high-voltage linear regulators with p reset and watchdog timer _______________________________________________________________________________________ 7 functional diagram reverse battery protection control logic bandgap reference 200ms timeout period mux out wa tchdog timer and logic reset thermal sensor current sensor and regulator en hold in +6.5v to +65v out to internal shutdown circuitry wdi* *max5023 only. set (max5024 only) +2.5v to +11v gnd r1 r2 4 a amp comp figure 1. functional diagram
max5023/max5024 reset output the reset supervisor circuit is fully integrated in the max5023/max5024 and uses the same reference volt- age as the regulator. reset asserts during power- up/down and brownout conditions. reset goes low if v out drops below the preset output voltage threshold, and remains low for 200ms (reset timeout period, t rp ) after v out rises above the reset voltage threshold. for the max5023 only, reset also asserts when wdi does not transition for 1.6s (watchdog timeout period, t wd ). two supply tolerance reset thresholds, -7.5% and -12.5%, are available for each device type. watchdog timer (max5023 only) a watchdog timer asserts reset if the watchdog input (wdi) is not toggled for 1.6s (watchdog timeout period, t wd ). reset remains low for 200ms (reset timeout peri- od, t rp ). if the watchdog is not updated for lengthy periods of time, the reset output appears as a pulse train, asserted for 200ms, deasserted for 1.6s, until wdi is toggled again. once reset asserts, it stays low for the entire reset timeout period ignoring any wdi transi- tions during the reset timeout period. figure 2 shows the watchdog operation timing diagram. to prevent the watchdog from asserting reset , toggle wdi with a valid rising or falling edge prior to t wd (min) = 1.12s. the watchdog counter clears when wdi toggles prior to t wd or when reset asserts. the watchdog resumes counting after reset deasserts. enable and hold inputs the max5023/max5024 support two logic inputs, en (active high) and hold (active low), making these devices ?utomotive friendly.?for example, the ignition drives en high, the regulator turns on and remains on even if en goes low, as long as hold is forced low and stays low after initial regulator power-up. this fea- ture makes it possible to implement a self-holding circuit without external components. release hold (an internal current source connects hold to out) to turn the regulator off. force en low and hold high to place the max5023/ max5024 into shutdown mode. shutdown mode draws less than 16? of supply current. table 1 shows the state of the regulator output with respect to the voltage level at 65v, low-quiescent-current, high-voltage linear regulators with p reset and watchdog timer 8 _______________________________________________________________________________________ v out when watchdog is held high and en = high v out when watchdog is held low and en = high batt batt batt batt por normal operation wdi held high por normal operation wdi held low en wdi reset v out ov ov ov ov ov ov v in en wdi reset v out v in figure 2. watchdog operation timing diagram
en and hold . figure 3 shows the timing diagram for the enable and hold functions. connecting hold to out or floating hold allows the en input to act as a standard on/ off switch for the regulator output. thermal protection when the j unction temperature exceeds t j = +150?, an internal thermal sensor signals the shutdown logic that turns off the pass transistor and allows the ic to cool. the thermal sensor turns the pass transistor on again after the ic? junction temperature cools by 20?, result- ing in a cycled output during continuous thermal-over- load conditions. thermal protection protects the max5023/max5024 in the event of fault conditions. for continuous operation, do not exceed the absolute maxi- mum junction temperature rating of t j = +150?. applications information output voltage selection (max5024 only) the max5024 features dual mode operation: it oper- ates in either a preset voltage mode or an adjustable mode. in preset voltage mode, internal trimmed feed- back resistors set the max5024? internal linear regulator to +3.3v or +5v (see the selector guide ). max5023/max5024 65v, low-quiescent-current, high-voltage linear regulators with p reset and watchdog timer _______________________________________________________________________________________ 9 dual mode is a trademark of maxim integrated products, inc. v reset v out v hold 0.2v 200ms v th >10 s >10 s 1) 2) 3) 4) 6) 7) 8) 9) 5) v out (nom) v hold, hold v hold, rel v en, off v en, on 1) enable active 2) hold inactive, pulled up by v out 3) power-on reset 4) hold active, clamped to gnd by external p 5) enable inactive, clamped by int, pulldown resistor 6) pulse width smaller than 10 s 7) hold inactive, released by p 8) regulator output shutdown 9) output-low reset v en v in figure 3. enable and hold behavior
max5023/max5024 select preset voltage mode by connecting set to ground. in adjustable mode, select an output between +2.5v and +11v using two external resistors connected as a voltage-divider to set (figure 4). set the output voltage using the following equation: v out = v set (1 + r1 / r2) where v set = 1.248v and r2 ? 100k ? . available output current calculation the max5023/max5024 high-voltage regulator pro- vides up to 150ma of output current. the input voltage extends to +65v. package power dissipation limits the amount of output current available for a given input/ output voltage and ambient temperature. figure 5 depicts the maximum power dissipation curve for these devices. the graph assumes that the exposed metal pad of the max5023/max5024 package is soldered to 1in 2 of pc board copper. use figure 5 to determine the allowable package dissi- pation for a given ambient temperature. alternately, use the following formula to calculate the allowable pack- age dissipation: after determining the allowable package dissipation, calculate the maximum output current using the follow- ing formula: the above equations do not include the negligible power dissipation from self-heating due to the ic ground current. i p v ma out max d in () ? -v out 150 p w for t c c for c c d a = + () +< + ? ? ? ? ? ? ? ? ? ? 1 538 70 1 538 70 70 125 . . - 0.01923 t - t aa 65v, low-quiescent-current, high-voltage linear regulators with p reset and watchdog timer 10 ______________________________________________________________________________________ in en gnd hold v out = v set (1 + r1 / r2) v set = 1.248v r2 = 1k ? to 500k ? set out reset to p 15 f r1 +6.5v to +65v +2.5v to +11v on off r2 max5024 10 f figure 4. setting the max5024 adjustable output voltage 10 20 30 40 50 60 70 80 90 100 110 120 130 140 150 0.2 0.4 0.6 0.8 1.0 1.2 1.4 1.6 1.8 2.0 t a ( c) p d (w) derate 19.23mw/ c 1.538w figure 5. maximum power dissipation vs. temperature table 1. truth table for regulator output state x = don? care. order en hold out comments 1 low x off initial state. en has 5m ? internal resistor to ground. hold has internal current source to out. 2 high x on regulator output is active when en is pulled high. 3 high low on hold is asserted forcing the regulator output on even if en goes low. 4x low on s el f- hol d i ng stat e. reg ul ator outp ut stays on r eg ar d l ess of the state of e n . 5 low high off regulator output is shutdown by releasing hold while en remains low.
example 1: t a = +95? v in = +14v v out = +5v find the maximum allowable output current. first calcu- late package dissipation at the given temperature as follows: then determine the maximum output current: example 2: t a = +125? v in = +14v v out = +3.3v calculate package dissipation at the given temperature as follows: and establish the maximum current: example 3: t a = +50? v in = +14v v out = +5v calculate package dissipation at the given temperature as follows: p d = 1.538w and find the maximum output current: in example 3, the maximum output current is calculated as 170.9ma, however, the maximum output current cannot exceed 150ma. use figure 6 to quickly deter- mine allowable maximum output current for selected ambient temperatures. capacitor selection and regulator stability for stable operation over the full temperature range and with load currents up to 150ma, use a 15? (min) output capacitor with an esr < 0.5 ? . to reduce noise and improve load-transient response, stability, and power-supply rejection, use larger output capacitor val- ues such as 22?. some ceramic dielectrics exhibit large capacitance and esr variation with temperature. for dielectric capacitors such as z5u and y5v, use 22? or more to ensure stability at temperatures below -10?. with x7r or x5r dielectrics, 15? should be sufficient at all oper- ating temperatures. for high-esr tantalum capacitors use 22? or more to maintain stability. to improve power-supply rejection and transient response use a minimum 10? capacitor between in and gnd. i w v ma i ma out max out max () () = () ()() = ? = 1 538 14 170 9 150 . . -5v i mw v ma out max () = () ()( ) = 480 4 14 44 89 . . - 3.3v pw mw d = () () = 1 538 25 480 4 . . - 0.01923w/ c 1 c - 70 c i w v ma out max () = () ()() = 1 057 14 117 4 . . -5v max5023/max5024 65v, low-quiescent-current, high-voltage linear regulators with p reset and watchdog timer ______________________________________________________________________________________ 11 maximum output current vs. input voltage max5023 fig04 v in (v) i out(max) (a) 65 60 5 10 15 25 30 35 40 45 50 20 55 0.02 0.04 0.06 0.08 0.10 0.12 0.14 0.16 0 070 v out = +5v device exposed p ad soldered to 1in 2 copper island t a = +70 c t a = +125 c t a = +85 c figure 6. maximum output current vs. input voltage pw w d = () () = 1 538 1 057 . . - 0.01923w/ c 95 c - 70 c
