    Hello Vengat,

    First of all, DRV8432 selection to drive BLDC motor is not right. DRV8432 suit for driving two DC motor or single bi-polar stepper motor. The right part to drive BLDC motor is DRV8332.

    In  DRV8332 as well as DRV8432, 12V can be supplied to PVDD and VDD/GVDD. Only precaution has to taken that on VDD/GVDD terminals, maximum voltage should not go higher than 13.2V.

    Best Regards
