Absolute Maximum Ratings (NON OPERATING)

Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress

ratings only. Functional operation of the device at these or any other conditions beyond those indicated under Operating

Conditions is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

Note (1): Jump Start: Vbat < 28V, 1 min, 1 pulse/h

Note (2): Low Battery mode guarantees operation when the battery voltage is below 6.5V; In this mode the output driver is

constantly on (100% PWM), Vpump-Vbat

≥ 4.0V at 250µA load on Pin OUT; the load current of VDD is limited to 2.5mA

Note (3): Low Drop voltage regulator; 40 mA max. external load at VDD; higher current with external transistor possible

Note (4): only as information. Will not be tested
