GND

Ground connection

IN1,2

Voltage controlled input pins with hysteresis, CMOS compatible. They Control

output switch state

CS1,2

Analog current sense pins, they deliver a current proportional to the load current

FR_Stby

In case of latch-off for overtemperature/overcurrent condition, a low pulse on the

FR_Stby pin is needed to reset the channel.

The device enters in standby mode if all inputs and the FR_Stby pin are low.
