Pin Description

Enable A (input): Logic-compatible enable input. (7526 active-high, 7536 active-low).

Do not float.

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

or thermal shutdown.

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

or thermal shutdown.

Enable B (Input): Logic-compatible enable input. (7526 active-high, 7536 active-low).

Do not float.

Switch Output B: Output MOSFET source. Typically connect to switched side of load.

Ground: Supply return.

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

Connect to positive supply.

Switch Output A: Output MOSFET source. Typically connect to switched side of load.
