Name

Function

VCC

Battery connection.

OUTPUT0,1,2,3

Power output.

GND

Ground connection.

INPUT0,1,2,3

Voltage controlled input pin with hysteresis, compatible with 3 V and 5 V CMOS

outputs. They control 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

LED0,1

Active high compatible with 3 V and 5 V CMOS outputs pin; they enable the LED

mode on logic high level (see Table 15: "Truth table").

SEL0,1,2

Active high compatible with 3 V and 5 V CMOS outputs pin; they address the

MultiSense multiplexer (see Table 15: "Truth table").

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.
