DRV8301:Is it possible to design separation of control power and main power?

hello?
We are developing a small DC MOTOR drive using the DRV8301.
If you want to separate the control power and motor power, please check if it is possible to separate the power if PVDD1 and PVDD2 are supplied separately.

    Hi Shin,

    Thank you for posting to the Motor Drivers forum!

    Yes, PVDD1 and PVDD2 can be powered separately as PVDD1, which is used to power the motor driver, is independent of PVDD2, which is used to power the buck converter.
