NAME

FUNCTION

12

IN

Input. Bypass with a 0.1µF ceramic capacitor to ground as close to the device

as possible.

2

5

GND

Ground

3

6

ON

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

44

FLAG

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.

5

3

OUT

Switch Output. Bypass with a 0.1µF ceramic capacitor to ground as close to

the device as possible.
