* Maximum value of operating supply voltage 1 (VCC) can not supply to STK672-630C-E, depending on motor current
value. Refer to “8. Precautions, etc” of Usage Notes.
*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.
