My interface to the DRV8833 is a micro controller running at 3.3VDC. The DRV8833 has a separate 6VDC supply, but the nFault line is pulled-up to the 3.3VDC micro supply. I would like to disable the 6V supply during idle time. Is there a problem with pulling the nFault line to 3.3V when the chip is not powered? Also, on power-up, there is a delay between the time the 3.3V is active and the 6V (DRV8833 supply) is enabled (due to soft start).
Thanks,
Doane
