DRV10987: PWM Steps

Mark Ackerson

Part Number: DRV10987

Customer has DRV10987 controlled motor up and running. They have concerns over the PWM range on the part. Datasheet seems to indicate 512 steps, but they only see the motor react to 256 steps. Any thoughts on this? Or potential for this to change in the future?

Hi Mark,

I checked with our design team for the DRV10987 and confirmed that the device has a 9 bit(512 steps) resolution for the SPEED pin. How were they conducting their test to determine the resolution of the SPEED pin?

Michael
