Notes:

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

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

3. With thermal contact to PCB. See thermal considerations section.

4. Pulse width <300µs with < 2% duty cycle.

5. Continuous body diode current conduction (reverse conduction, i.e. VOUT to VIN) is not recommended.

6. Devices are ESD sensitive. Handling precautions recommended. HBM (Human body model), 1.5kΩ in series with 100pF.

7. Measured on the MIC94040YFL and MIC94042YFL.
