may cause permanent damage to the device. This is a stress IN Voltage rating only; functional operation of the device at these or any Continuous −0.3 V to +40 V other conditions above those indicated in the operational Peak (<100 ms) −0.3 V to +60 V section of this specification is not implied. Exposure to absolute BOOST Voltage maximum rating conditions for extended periods may affect Continuous −0.3 V to +45 V device reliability. Peak (<100 ms) −0.3 V to +65 V
