IN_PullUP
Connection to optional external pull-up resistor for open load
detection in off-state.
+5V
5V Power Supply
FaultRST
Active low compatible with 3V and 5V CMOS outputs pin; it
unlatches the output in case of fault; If kept low, sets the
outputs in auto-restart mode.
Multiplexed analog sense output pin; it delivers a current
MultiSense proportional to the selected diagnostic: load current, supply
voltage or chip temperature.
S_EN
Active high compatible with 3V and 5V CMOS outputs pin; it
enables the MultiSense diagnostic pin.
SEL0,1,2
Active high compatible with 3V and 5V CMOS outputs pin;
they address the MultiSense multiplexer.
IN0,1,2,3
Voltage controlled input pin with hysteresis, compatible with
3V and 5V CMOS outputs. They control output switch state.

In case the user wishes to utilize the Current Sense/MultiSense function of the device, it is
necessary to plug a sense resistor in R_SENSE.
The package includes a through-hole resistor, to be mounted on TP1-TP2 (see Figure 4:
"Mounting through-hole sense resistor").
