Pin Description

Name

Function

IN

Input voltage; connect a 0.1μF or greater ceramic capacitor from IN to GND as close to the

IC as possible.

GND

Ground pin.

EN

Enable input, logic high turns on power switch.

EN

Enable input, logic low turns on power switch.

FAULT

Active-low open-drain output, asserted during over current, over temperature, or

reverse-voltage conditions.

ILIM

External resistor used to set current-limit threshold; recommended 15kΩ ≤ RILIM ≤ 64kΩ.

OUT

Power-switch output.
