Name
Function
VCC
Battery connection.
OUTPUT0,1 Power output.
GND
Ground connection. Must be reverse battery protected by an external diode / resistor network.
INPUT0,1
Voltage controlled input pin with hysteresis, compatible with 3 V and 5 V CMOS outputs. It controls output switch
state.
CS
Multiplexed analog sense output pin; it delivers a current proportional to the selected load current.
SEn
Active high compatible with 3 V and 5 V CMOS outputs pin; it enables the CS diagnostic pin.
SEL
Active high compatible with 3 V and 5 V CMOS outputs pin; it addresses the CS multiplexer.
FaultRST
Active low compatible with 3 V and 5 V CMOS outputs pin; it unlatches the output in case of fault; If kept low, it
sets the outputs in auto-restart mode.
