Notes: 1. Absolute maximum ratings are those values beyond which the device could be permanently damaged.

Absolute maximum ratings are stress ratings only and functional device operation is not implied.

2. The thermal shutdown set to 160°C (typical) avoids irreversible damage on the device due to power

dissipation.
