6.1 Absolute Maximum Ratings

Over operating free-air temperature range (unless otherwise noted)(1)(2)
MIN MAX UNIT
Motor power-supply voltage VM –0.3 12 V
Logic power-supply voltage VCC –0.3 7 V
Control pin voltage IN1, IN2, nSLEEP –0.5 7 V
Peak drive current OUT1, OUT2 Internally limited A
Operating virtual junction temperature, TJ –40 150 ºC
Storage temperature, Tstg –60 150 ºC
(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) All voltage values are with respect to network ground pin.

6.2 ESD Ratings

VALUE UNIT
