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 MIC252x-1. Off is ≥ 2.4V and on is ≤ 0.8V for the MIC252x-2. The enable input has approximately 200mV
of hysteresis. See control threshold charts.
