IN

Switch Output. Bypass with a 0.1µF capacitor to ground.

Ground

Fault Output. This open-drain output goes low when the device stays in forward or reverse

current limit for more than the blanking time period. FLAG is high impedance when a fault is

not present or when ON is low.

Active-High Switch-On Input. A logic high turns the switch on.

Input. Bypass with a 0.1µF ceramic capacitor to ground.
