My customer is using DRV10866

Could you let me know the method of BEMF detection, please?

-> Compare voltage of COM pin and shut-off phase pin(W or U or V)?

Best regards,

Shimizu-san,

In each commutation state, there is one phase off. We are comparing the off phase to COM to get BEMF zero crossing information.

Thanks,

Seil
