Function
These pins are the input to the P-channel MOSFET source. Connect a
1µF capacitor from IN to GND.
Active low enable input. A logic low turns the switch on.
Ground.
Current limit set input. A resistor from SET to ground sets the current limit
for the switch.
These pins are the P-channel MOSFET drain connection. Connect a 1µF
capacitor from OUT to GND.
Fault indication output. This open-drain output goes low when in current
limit or when the die temperature exceeds +135ºC, with a 2ms delay after
the fault event occurs.
