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.
Specification for packaged product only.
The application is fully functional at low IN (supply of the control section) if the external MOSFETs have enough low voltage V
The current will come only from the internal 100kΩ pull-up resistor sitting on the EN Input and tied to IN.
