Hi Anuj,
Today I did lots of tests. I found phase voltage will increase noise when increasing torque. When the current reached up to around 10A, the phase peak-to-peak voltage will over 65V. That caused OC happens. So do you have any better idea to reduce the noise? what should I improve when I re-design the board?
I checked the other board which doesn't use DRV8303. The other board also has that kind of noise. But their gate driver can handle those noise.
Thanks,
Li
