Function

1,2

IN

These pins are the input to the P-channel MOSFET source. Connect a

1µF capacitor from IN to GND.

3

ON

Active-Low Enable Input. A logic low turns the switch on.

4

GND

Ground

5

SET

Current-Limit Set Input. A resistor from SET to ground sets the current

limit for the switch.

6,7

OUT

These pins are the P-channel MOSFET drain connection. Connect a 1µF

capacitor from OUT to GND.

8

FAULT

Fault-Indication Output. This open-drain output goes low when in current

limit or when the die temperature exceeds +135 ºC, with a 2ms delay

after the fault event occurs.
