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.

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,

sets the outputs in auto-restart mode.
