(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) The negative spike less than –5 V and narrower than 50-ns duration should not cause any problem.
RECOMMENDED OPERATING CONDITIONS
Supply voltage, VM for motor control
Supply voltage for DC-DC converter (VDIN)
Average output current for motor driver for each H-bridge
DC output current for DC-DC converter
