Exceeding the absolute maximum rating may damage the device.
The device is not guaranteed to function outside its operating rating.
Devices are ESD sensitive. Handling precautions recommended. Human body model, 1.5k in series with 100pF.
Off is ≤ 0.8V and on is ≥ 2.4V for the MIC2525-1. Off is ≥ 2.4V and on is ≤ 0.8V for the MIC2525-2. The enable input has approximately
200mV of hysteresis. See control threshold charts.
