6 Specifications

6.1 Absolute Maximum Ratings(1)(2)

MIN MAX UNIT
Power supply voltage, VCC –0.3 7 V
Digital input pin voltage –0.5 VCC + 0.5 V
Peak motor drive output current Internally limited A
Continuous motor drive output current per H-bridge(3) –1.5 1.5 A
TJ Operating junction temperature –40 150 °C
Tstg Storage temperature –60 150 °C
(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 pertain to network ground terminal.
(3) Power dissipation and thermal limits must be observed.

6.2 ESD Ratings
