DRV8350: Questions about DRV8350S circuit connection

Hi team,

I would like to ask you a question about the circuit connection of DRV8350S.

Should the 30pin GND of DRV8350S be connected to the power GND? Or should I connect it to signal GND?

    Hi Yamadadai, 

    Pin 30, GND, is recommended to be connected to the system-level ground of the PCB.  If you have a split ground architecture for your system, It should most likely be connected to the power ground.

    Best Regards,
