Team,

On DRV8706 or DRV8702: Can different power rail be used for VM and VBAT?
Typically for this application VM would be 24V and VBAT could vary between 0 and 24V.

If not what would be the best alternative for such scheme with a Full bridge driver?

Thanks in advance!

Hi A,

I will check for you - off the top if my head, there could be an issue where VM and VDRAIN must be within +/- 10V in the abs max ratings table.

Regards,
Mike

Hi again,

Sorry for the long delay - I noticed you had another internal thread with the team on the same topic. Can we close out this thread?

Regards,
Mike
