Input, connect a 0.1µF or greater ceramic capacitor

from IN to GND as close to IC as possible.

GND

— Ground, connect to external exposed pad.

—

I Enable input, logic low turns on power switch.

—

I Enable input, logic high turns on power switch.

FAULT

Active-low open-drain output, asserted during over-

current, over-temperature, or reverse-voltage

conditions.

ILIM

Use external resistor to set current-limit threshold;

recommended 10kΩ ≦ RLIM ≦ 210kΩ

OUT

Voltage Output Pin, connect a 0.1μF bypass capacitor

and a high-value capacitor to GND, close to IC. (At

least 10μF in USB application.)

Exposed

Pad

Pad

—

Internal connection to GND; Connect to GND externally

for improved power dissipation. It should not be used

as electrical ground conduction path.
