Hysteresis

Notes:

1. Exceeding the absolute maximum rating may damage the device.

2. The device is not guaranteed to function outside its operating rating.

3. Devices are ESD sensitive. Handling precautions recommended. Human body model, 1.5k in series with 100pF.

4. Off is

≤0.8V

and on is

≥2.4V

for the MIC2544A-1 and MIC2548A-1. Off is

≥2.4V

and on is

≤0.8V

for the MIC2544A-2 and MIC2548A-2. The enable

input has about 200mV of hysteresis.

5. Guaranteed by design but not production tested.

6. Current limit threshold is determined by I
