Hi team,

I have a simple question.

Is there any issue during PVDD turn off and applying 3.3V to nFault and nSCS, VREG, PWRGD pin?

Could you give me your advice.

Regards,

Yoshi

Hi Takahashi-san,

Assuming you are referring to the DRV8305N, there are no reliability issues.

There can be extra current flow in the nSCS pulldown resistor and VREF
