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.

4. Specification for packaged product only.

5. If there is a fault on one channel, that channel will shut down when the die reaches approximately 140°C. If the die reaches

approximately 160°C, both channels will shut down, even if neither channel is in current limit.
