1.0 and on is
≥2.5V.
For the G525A2, off is
≥
2.5V and on is
≤

PIN FUNCTION
Enable (input):
Logic level enable input. High input >2.4V typical.
Low input <2.2V typical (1 for active high, 2 for active low).
Make sure EN never floating.
Open-Drain Fault Flag (Output):
Active-low, open-drain output. Indicates overcurrent,
thermal shutdown and UVLO.
Ground.
Not internally connected.
Input Supply:
Output MOSFET source, which also supplies IC's internal circuitry. Con-
nect to positive supply.
Switch Output:
Output MOSFET drain. Typically connect to switched side of load.
