Battery connection
Power output
Ground connection; must be reverse battery protected by an external
diode/resistor network
Voltage controlled input pin with hysteresis, CMOS compatible; controls
output switch state
Analog current sense pin; delivers a current proportional to the load
current
Active high CMOS compatible pin to disable the current sense pin
