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 circuit (operating temperature is more than 150 °C typ.) builds in this product.
