MIC5016/5017 micrel october 1998 5 MIC5016/5017 applications information functional description the MIC5016 is functionally compatible with the mic5012, and the mic5017 is an inverting configuration of the MIC5016. the internal functions of these devices are controlled via a logic block (refer to block diagram) connected to the control input (pin 14). when the input is off (low for the MIC5016, and high for the mic5017), all functions are turned off, and the gate of the external power mosfet is held low via two n- channel switches. this results in a very low standby current; 15 a typical, which is necessary to power an internal bandgap. when the input is driven to the on state, the n-channel switches are turned off, the charge pump is turned on, and the p-channel switch between the charge pump and the gate turns on, allowing the gate of the power fet to be charged. the op amp and internal zener form an active regulator which shuts off the charge pump when the gate voltage is high enough. this is a feature not found on the mic5012. the charge pump incorporates a 100khz oscillator and on- chip pump capacitors capable of charging a 1,000pf load in 90 s typical. in addition to providing active regulation, the internal 15v zener is included to prevent exceeding the v gs rating of the power mosfet at high supply voltages. the MIC5016/17 devices have been improved for greater ruggedness and durability. all pins can withstand being pulled 20 v below ground without sustaining damage, and the supply pin can withstand an overvoltage transient of 60v for 1s. an overvoltage shutdown has also been included, which turns off the device when the supply reaches 35v. construction hints high current pulse circuits demand equipment and assembly techniques that are more stringent than normal, low current lab practices. the following are the sources of pitfalls most often encountered during prototyping: supplies : many bench power supplies have poor transient response. circuits that are being pulse tested, or those that operate by pulse-width modulation will produce strange results when used with a supply that has poor ripple rejection, or a peaked transient response. always monitor the power supply voltage that appears at the drain of a high side driver (or the supply side of the load for a low side driver) with an oscilloscope. it is not uncommon to find bench power supplies in the 1kw class that overshoot or undershoot by as much as 50% when pulse loaded. not only will the load current and voltage measure- ments be affected, but it is possible to overstress various components, especially electrolytic capacitors, with possibly catastrophic results. a 10 f supply bypass capacitor at the chip is recommended. residual resistances : resistances in circuit connections may also cause confusing results. for example, a circuit may employ a 50m ? power mosfet for low voltage drop, but unless careful construction techniques are used, one could easily add 50 to 100m ? resistance. do not use a socket for the mosfet. if the mosfet is a to- 220 type package, make high current connections to the drain tab.wiring losses have a profound effect on high-current circuits. a floating milliohmeter can identify connections that are con- tributing excess drop under load. low voltage testing as the MIC5016/5017 have relatively high output impedances, a normal oscilloscope probe will load the device. this is especially pronounced at low voltage operation. it is recommended that a fet probe or unity gain buffer be used for all testing. circuit topologies the MIC5016 and mic5017 are well suited for use with standard power mosfets in both low and high side driver configurations. in addition, the lowered supply voltage re- quirements of these devices make them ideal for use with logic level fets in high side applications with a supply voltage of 3v to 4v. (if higher supply voltages [>4v] are used with logic level fets, an external zener clamp must be supplied to ensure that the maximum v gs rating of the logic fet [10v] is not exceeded). in addition, a standard igbt can be driven using these devices. choice of one topology over another is usually based on speed vs. safety. the fastest topology is the low side driver, however, it is not usually considered as safe as high side driving as it is easier to accidentally short a load to ground than to v cc. the slowest, but safest topology is the high side driver; with speed being inversely proportional to supply voltage. it is the preferred topology for most military and automotive applications. speed can be improved consider- ably by bootstrapping the supply. all topologies implemented using these devices are well suited to driving inductive loads, as either the gate or the source pin can be pulled 20v below ground with no effect. external clamp diodes are unnecessary, except for the case in which a transient may exceed the overvoltage trip point. high side driver (figure 1) the high side topology shown here is an implementation of a sleep-mode switch for a laptop or notebook computer which uses a logic level fet. a standard power fet can easily be substituted when supply voltages above 4v are required. low side driver (figure 2) a key advantage of this topology, as previously mentioned, is speed. the mosfet gate is figure 2. low side driver load 1/2 MIC5016 off on +3v to +30v gate gnd source input v+ 10f
MIC5016/5017 micrel MIC5016/5017 6 october 1998 driven to near supply immediately when the MIC5016/17 is turned on. typical circuits reach full enhancement in 50 s or less with a 15v supply. bootstrapped high side driver (figure 3) the turn-on time of a high side driver can be improved to faster than 40 s by bootstrapping the supply with the mosfet source. the schottky barrier diode prevents the supply pin from dropping more than 200mv below the drain supply, and improves turn- on time. since the supply current in the off state is only a small leakage, the 100nf bypass capacitor tends to remain charged for several seconds after the MIC5016/17 is turned off. faster switching speeds can be obtained at the expense of supply voltage (the overvoltage shutdown will turn the part off when the bootstrapping action pulls the supply pin above 35v) by using a larger capacitor at the junction of the two 1n4001 diodes. in a pwm application (this circuit can be used for either pwm ed or continuously energized loads), the chip supply is sustained at a higher potential than the system supply, which improves switching time. figure 3. bootstrapped high-side driver high side driver with current sense (figure 4) although no current sense function is included on the MIC5016/17 de- vices, a simple current sense function can be realized via the addition of one more active component; an lm301a op amp used as a comparator. the positive rail of the op amp is tied to v + , and the negative rail is tied to ground. this op amp was chosen as it can withstand having input transients that swing below the negative rail, and has common mode range almost to the positive rail. the inverting side of this comparator is tied to a voltage divider which sets the voltage to v + v trip . the noninverting side is tied to the node between the drain of the fet and the sense resistor. if the overcurrent trip point is not exceeded , this node will always be above v + v trip , and the output of the compara- tor will be high which feeds the control input of the MIC5016 (polarities should be reversed if the mic5017 is used). once the overcurrent trip point has been reached, the comparator load 1/2 MIC5016 control input off on +2.75v to +30v gate gnd source input v+ 1f 100nf 1n4001 (2) 1n5817 irf540 will go low, which shuts off the MIC5016. when the short is removed, feedback to the input pin insures that the MIC5016 will turn back on. this output can also be level shifted and sent to an i/o port of a microcontroller for intelligent control. current shunts (r s ). low valued resistors are necessary for use at r s . resistors are available with values ranging from 1 to 50m ? , at 2 to10w. if a precise overcurrent trip point is not necessary, then a nonprecision resistor or even a measured pcb trace can serve as r s . the major cause of drift in resistor values with such resistors is temperature coefficient; the designer should be aware that a linear, 500ppm/ c change will contribute as much as 10% shift in the overcurrent trip point. if this is not acceptable, a power resistor designed for current shunt service (drifts less than 100ppm/ c), or a kelvin-sensed resistor may be used. ? load 1/2 MIC5016 gate gnd source input v+ 10f r4 1k ? r s 0.06 ? 12v on r1 1k ? r2 120k ? lm301a 2.2k ? i trip = v trip /r s = 1.7a v trip = r1/(r1+r2) figure 4. high side driver with overcurrent shutdown ? suppliers of precision power resistors: dale electronics, inc., 2064 12th ave., columbus, ne 68601.

MIC5016/5017 micrel MIC5016/5017 8 october 1998 motor driver with stall shutdown (figure 10) tachometer feedback can be used to shut down a motor driver circuit when a stall condition occurs. the control switch is a 3-way type; the start position is momentary and forces the driver on. when released, the switch returns to the run position, and the tachometer s output is used to hold the MIC5016 input on. if the motor slows down, the tach output is reduced, and the MIC5016 switches off. resistor r sets the shutdown threshold. figure 10. motor stall shutdown simple dc-dc converter (figure 11) the simplest applica- tion for the MIC5016 is as a basic one-chip dc-dc converter. as the output (gate) pin has a relatively high impedance, the output voltage shown will vary significantly with applied load. incandescent/halogen lamp driver (figure 8) the combi- nation of an MIC5016/5017 and a power fet makes an effective driver for a standard incandescent or halogen lamp load. such loads often have high inrush currents, as the resistance of a cold filament is less than one-tenth as much as when it is hot. power mosfets are well suited to this application as they have wider safe operating areas than do power bipolar transistors. it is important to check the soa curve on the data sheet of the power fet to be used against the estimated or measured inrush current of the lamp in question prior to prototyping to prevent explosive results. if overcurrent sense is to be used, first measure the duration of the inrush, then use the topology of figure 5 with the rc of the timer chosen to accomodate the duration with suitable guardbanding. figure 8: halogen lamp driver relay driver (figure 9) some power relay applications re- quire the use of a separate switch or drive control, such as in the case of microprocessor control of banks of relays where a logic level control signal is used, or for drive of relays with high power requirements. the combination of an MIC5016/ 5017 and a power fet also provides an elegant solution to power relay drive. figure 9: relay driver figure 11. dc - dc converter 1/2 MIC5016 control input off on irf540 12v gate gnd source input v+ 10f osram hlx64623 1/2 MIC5016 control input off on irf540 12v gate gnd source input v+ 10f guardian electric 1725-1c-12d 1/2 MIC5016 gate gnd source input v+ 10f 5v v out = 12v 1/2 MIC5016 irfz44 12v gate gnd source input v+ 10f m t r 330k ? 330k ? 1n4148
MIC5016/5017 micrel october 1998 9 MIC5016/5017 high side driver with load protection (figure 12) al- though the MIC5016/17 devices are reverse battery pro- tected, the load and power fet are not in a typical high side configuration. in the event of a reverse battery condition, the internal body diode of the power fet will be forward biased. this allows the reversed supply to drive the load. an mbr2035ct dual schottky diode was used to eliminate this problem. this particular diode can handle 20a continu- ous current and 150a peak current; therefore it should survive the rigors of an automotive environment. the diodes are paralleled to reduce the switch loss (forward voltage drop). figure 12: high side driver with load protection push-pull driver with no cross-conduction (figure 13) as the turn-off time of the MIC5016/17 devices is much faster than the turn-on time, a simple dual push-pull driver with no cross conduction can be made using one MIC5016 and one mic5017. the same control signal is applied to both inputs; the MIC5016 turns on with the positive signal, and the mic5017 turns on when it swings low. figure 13: push-pull driver this scheme works with no additional components as the relative time difference between the rise and fall times of the mic5014 is large. however, this does mean that there is considerable deadtime (time when neither driver is turned on). if this circuit is used to drive an inductive load, catch diodes must be used on each half to provide an alternate path for the kickback current that will flow during this deadtime. this circuit is also a simple h-bridge which can be driven with a pwm signal on the input for smps or motor drive applica- tions in which high switching frequencies are not desired. synchronous rectifier (figure 14) in applications where efficiency in terms of low forward voltage drops and low diode reverse-recovery losses is critical, power fets are used to achieve rectification instead of a conventional diode bridge. here, the power fets are used in the third quadrant of the iv characteristic curve (fets are installed essentially back- wards ). the two fets are connected such that the top fet turns on with the positive going ac cycle, and turns off when it swings negative. the bottom fet operates opposite to the top fet. in the first quadrant of operation, the limitation of the device is determined by breakdown voltage. here, we are limited by the turn-on of a parasitic p-n body drain diode. if it is allowed to conduct, its reverse recovery time will crowbar the other power fet and possibly destroy it. the way to prevent this is to keep the ir drop across the device below the cut-in voltage of this diode; this is accomplished here by using a fast comparator to sense this voltage and feed the appropriate signal to the control inputs of the MIC5016 device. obviously, it is very important to use a comparator with a fast slew rate such as the lm393, and fast recovery diodes. 3mv of positive feedback is used on the comparator to prevent oscillations. at 3a, with an r ds (on) of 0.077 ? , our forward voltage drop per fet is ~ 0.2 v as opposed to the 0.7 to 0.8 v drop that a normal diode would have. even greater savings can be had by using fets with lower r ds (on)s, but care must be taken that the peak currents and voltages do not exceed the soa of the chosen fet. figure 14: high efficiency 60 hz synchronous rectifier load 1/2 MIC5016 control input off on irf540 12v nc gate gnd source input v+ nc nc 10f mbr2035ct MIC5016 control input 1 12 10 3 11 irfz40 12v gate a source b gnd in b in a v+ a source a gate b 10f mic5017 12 10 14 11 4 2 6 5 gate a gate b in b in a v+ b v+ a source a source b 12v irfz40 v out b gnd 3 v+ b control input 2 14 v out a irfz40 irfz40 4 2 6 5 MIC5016 12 10 11 3 4 2 6 5 gate a gate b gnd in b in a v+ a source a source b 10f v+ b 14 56k ? 10 ? 110v ac caltronics t126c3 25.2v v ct 30m ? 10k ? 10k ? 1/2 lm393 1n914 (2) 1k ? 1k ? * 1n914 1rf540 4700f v out = 18v, 3a * 1rf540 1n914 * parasitic body diode
