Part Number: DRV8332

Hi support team.

My customer is considering a unique power sequence below.

Are there any concerns about this unique behavior of PVDD?

Best regards,

Hi Daisuke,

This should be okay as long as the customer is not concerned about the potential 1.2mA leakage current path out from the PVDD pins when GVDD = 12V and PVDD is off. https://e2e.ti.com/support/motor-drivers-group/motor-drivers/f/motor-drivers-forum/1081412/drv8332-leakage-current-from-pvdd/4024961#4024961

Thanks,
Aaron
