* Devices are ESD protected, however, handling precautions are recommended.
** For the G525A1, off is ≤ 1.0 and on is ≥2.5V. For the G525A2, off is ≥ 2.5V and on is ≤ 1.0V. The enable input,
CTRL, has approximately 200mV of hysteresis.

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.
