Pin Description

Pin Number

Pin Name

Pin Function

1 / 4

EN(A/B)

Enable (Input): Logic-compatible enable input. High input > 2.1V typical.

Low input <1.9V typical (-1 active high, -2 active low). Do not float.

2 / 3

FLG(A/B)

Fault Flag (Output): Active-low, open-drain output. Indicates overcurrent,

UVLO, and thermal shutdown.

6

GND

Ground: Supply return.

7

IN

Supply Input: Output MOSFET drain. Also supplies IC’s internal circuitry.

Connect to positive supply.

8 / 5

OUT(A/B)

Switch Output: Output MOSFET source. Typically connect to switched side

of load.
