Symbol

Name and function

1, 2

IN

Input P-channel MOSFET source. Bypass IN with a 1

μF

capacitor to ground

3ON

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.

limit in Amperes

8FAULT

Fault indicator output. This open drain output goes low

when in current limit or when the die temperature exceeds

135 °C
