DRV11873: Rotation speed reaches 0.01% accuracy

Part Number: DRV11873
Other Parts Discussed in Thread: DRV10970,

Hi Team,

For 3W small motor in 300 rotating speed, could we reach 0.01% accuracy, which means 0.03?

Do you any recommendation?

    Hi Amelie,

    Thanks for posting your question in MD forum. What is the end application? DRV11873 is a sensorless driver and it cannot guarantee 0.01% accuracy. If you are looking for integrated control motor drivers, I would recommend using sensored drivers such as DRV10970. 

    Regards,
