* Operation at the maximum VCC value may not be possible, depending on the motor current. See “8. Other Notes on

Use” in the Data Sheet for details.

*Ioave values are for when the lead frame of the product is soldered to the mounting substrate.

Notes: A fixed-voltage power supply must be used.

Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the Recommended Operating

Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect device reliability.
