Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the

Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect

device reliability.

2. The thermal shutdown set to 160

°C (typical) avoids irreversible damage on the device due to power dissipation. For further information see
