Datasheet
e) f) PWM control mode A
The rotational speed of the motor can be controlled by the duty cycle of the PWM signal fed to the FIN pin or the
RIN pin. In this mode, the high side output is fixed and the low side output is switching, corresponding to the input
signal. The state of the output toggles between "L" and "Hi-Z".
The frequency of the input PWM signal can be between 20kHz and 100kHz. The circuit may not operate properly for
PWM frequencies below 20kHz and above 100kHz. Note that control may not be attained by switching on duty at
frequencies lower than 20kHz, since the operation functions via the stand-by mode. To operate in this mode,
connect the VREF pin to the VCC pin. In addition, establish a current path for the recovery current from the motor,
by connecting a bypass capacitor (10μF or higher is recommended) between VCC and ground.
