DRV8706-Q1: DRAIN pin voltage limits

Hi all,

I would like to separate the DRAIN pin from the Pvdd pin. I find little or no info about it in the datasheet.

Preferably I need to have a regulated 7..8 Volt supply on Pvdd. And DRAIN (and halfbridge) are connected to a battery which can range from 8 to 13 volt.

Is that possible , or will it cause other problems.
