Ground connection
Voltage controlled input pins with hysteresis, CMOS compatible. They control output
switch state
Analog current sense pins, they deliver a current proportional to the load current
In case of latch-off for overtemperature/overcurrent conditions, 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.
