Part Number:DRV8320R
We have EMC issues on our DRV8301 based motor controller so we have to do minor modifications on our cramped board. DRV8320R is more robust and physically smaller, enabling more room for better power routing, and extra EMC filters & snubbers. Somewhat lower cost also helps.
However, the datasheet of DRV8301 is 39 pages while DRV832x is 90 with a lot of new info. So I am a bit frightened that we will miss important stuff if we decide to upgrade the DRV IC. Does there exist any recommendation or examples on how to upgrade schematic/layout/software to accommodate such an upgrade? If not, I believe a simple check list for potentially needed hardware and software changes would be very useful.
Thank you & regards,
