6.1 Absolute Maximum Ratings

See (1)(2)
MIN MAX UNIT
Power supply voltage, VM –0.3 12 V
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 are with respect to network ground terminal.
(3) Power dissipation and thermal limits must be observed.

6.2 ESD Ratings

VALUE UNIT

Charged-device model (CDM), per JEDEC specification JESD22-C101(2) ±1500
(1) JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process.
(2) JEDEC document JEP157 states that 250-V CDM allows safe manufacturing with a standard ESD control process.
