Figure 1. Pin assignment (Top view)

Name

Description

IN

Input voltage, connect a 0.1 μF 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.

——————

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 10 kΩ ≤ RILIM ≤ 130 kΩ.

OUT

Power switch output.

Thermal pad

(GND)

Internally connect to GND. Recommend to connect to a large ground plane for the improved thermal

performance.
