DRV8718-Q1: VAREF=5V, VDVDD=3.3V

Part Number: DRV8718-Q1

Tool/software:

Hello team,

Is it ok to configure VAREF=5V and VDVDD=3.3V? Any risk because I am not sure if the sensing output will be connected to other internal blocks, or just output?

In low power mode, the VAREF=5V will be shut down, and VDVDD is still on, is it acceptable?

Thanks!

Regards,

Daniel Wang

    Hi Daniel,

    Thank you for your questions. 

    VAREF=5Vand DVDD=3.3V is no problem. 

    >>In low power mode, the VAREF=5V will be shut down, and VDVDD is still on, is it acceptable?

    This is also no issue. AREF is used for current sense amp's offset adjustment.

    regards
