Other Parts Discussed in Thread: DRV8350
Hi,
I have a customer that has a design for DRV8320 and would like to convert to DRV8350, but is constrained on making changes on the PCB.
Is there a suggested way to do this?
Thank you.
Regards,
Alberto

Hi Alberto,
The pinouts are very similar, but not completely identical for devices without the buck regulator integrated.
If you are planning on making an adapter board from an existing layout to DRV835x, I would recommend putting the passive components for the DRV onto the adapter board, because we do see issues when bypass capacitors are too far away from the DRV.
Please see attached for a proposal to create a board layout supporting both DRV8320 and DRV8350:

Hi Matt,
thanks for sharing this. Is there a layout example or unfinished board files available for this?
Thank you!

Hi Alberto,
This was developed with the datasheet pinouts, not an actual layout file.
I would recommend referencing the BOOSTXL-DRV8320H and DRV8350H-EVM for example layouts.
Thanks,
Matt
