DRV8825: Recommended circuits for EMC

Hi Team,

Using the circuit diagram in the DRV8825 specification sheet, the motor can run with radiation causing the FCC to fail. With the other conditions unchanged, the FCC can be passed by unplugging the motor cable.

Would it be possible to share some recommended EMC circuits and improvements?

Working voltage is 12V, 32 microsteps, IFS = 1A, decay mode, mixed decay. 

Could you please help check this case? Thanks.

Best Regards,

Cherry
