General Note: Devices are ESD protected, however, handling precautions recommended.

Note *: Off is

≤ 1.0 and on is ≥2.4V for the G526-1. Off is ≥ 2.4V and on is ≤ 1.0V for the G526-2. The enable input

has approximately 200mV of hysteresis. See control threshold charts.

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 source. Also supplies IC's internal circuitry. Connect to

positive supply.

8/5

OUT(A/B)

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