Symbol
Name and function
1, 2
IN
Input P-channel MOSFET source. Bypass IN with a 1 μF
capacitor to ground
3
ON
Active low switch ON input. A logic low turns the switch ON
4
GND
Ground
5
SET
Set current limit input. A resistor from SET to GND sets the
current limit for the switch.
6,7
OUT
Switch output. P-channel MOSFET drain. Bypass OUT with
a 0.1 μF capacitor to ground
Fault indicator output. This open drain output goes low
8
FAULT
when in current limit or when the die temperature exceeds
135 °C
