Pin Function
Resets current sense latch and turns on power MOSFET when taken above
threshold (3.5V typical). Pin 1 requires <1µA to switch.
Sets current sense trip voltage according to:
where R

stant.

clamp zener. Connect to the load side of current shunt or kelvin lead of cur-
rent sensing FET. Pins 3 and 4 can safely swing to –10V when turning off
inductive loads.
Drives and clamps the gate of the power FET. Pin 6 will be clamped to ap-
proximately –0.7V by an internal diode when turning off inductive loads.
Supply pin; must be decoupled to isolate from large transients caused by
the power FET drain. 10µF is recommended close to pins 7 and 5.
Outputs status of protection circuit when pin 1 is high. Fault low indicates
normal operation; fault high indicates current sense tripped.
