DRV2603EVM-CT: Control the strength of vibration by DRV2603

Hi. I want to make 3 levels of vibration on the device (low, middle, high), so can I control the strength of vibration with DRV2603 by changing the PWM duty cycle?

    Hi Anar,

    That's correct. Changing the duty cycle will change the vibration strength, this is according to figures 11 and 12 from data sheet depending on the actuator (LRA or ERM).
