Notes:

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

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

3. The device is not guaranteed to function outside operating range.

4. Specification for packaged product only.

5. The application is fully functional at low VDD (supply of the control section) if the external MOSFETs have low voltage VTH.
