Product List
Changing the PWM ON duty based on the supplied DC voltage value makes it possible to control motor speed. This method (PWM duty control) results in lower power consumption compared with controlling the voltage supplied to the motor. Some ROHM DC motor drivers offer two ways of using this PWM: the Standard is to apply PWM signals directly from MCU on FIN and RIN pins and the second way is the VREF Control to apply DC voltage VREF, this PWM will be created internally from VREF.
