Hi Team,

Could you possible help to check if DRV8343-Q1 could detect the phase voltage cross zero point? Thanks a lot for your support.

Hey Jie,

Thank you for your patience.

I would like to ask for some clarification on what you meant by phase voltage cross zero point?

Our Drv8x devices do not measure phase voltage, if that is what you intended. Our drivers utilize CSAs to measure phase current. You could utilize them to indirectly measure voltage using an external circuitry if you are interested.

Best Regards,

Akshay

Hi Akshay,

Thanks a lot for your feedback. Your answer could solve my question.

The phase voltage refers to the motor point A, point B, point C voltage.
