Application Circuit Example
PWM signal
FG signal
Note 1: Take enough care in designing output V
Note 2: The above application circuit and values mentioned are just an example for reference. Since the values may
fault or GND fault which may cause the IC to break down.
vary depending on the motor to be used, appropriate values must be determined through experiments before
using the device.
