(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) All voltage values are with respect to GND.
(3) For proper operation of the TL7702A, the voltage applied to the SENSE terminal should not exceed VCC − 1 V or 6 V, whichever is less

6.2 ESD Ratings
