Name
Function
VCC
Battery connection.
OUTPUT0,1,2,3
Power output.
GND
Ground connection. Must be reverse battery protected by an external
diode / resistor network.
INPUT0,1,2,3
Voltage controlled input pin with hysteresis, compatible with 3 V and 5 V
CMOS outputs. It controls output switch state.
MultiSense
Multiplexed analog sense output pin; it delivers a current proportional to
the selected diagnostic: load current, supply voltage or chip temperature.
SEn
Active high compatible with 3 V and 5 V CMOS outputs pin; it enables
the MultiSense diagnostic pin.
SEL0,1,2
Active high compatible with 3 V and 5 V CMOS outputs pin; they address
the MultiSense 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.
