Tool/software:
Hi Team,
In my custom board, I have both the DRV8873HPWPRQ1 (H-bridge motor driver for brushed DC motors) and the DRV8312 (3-phase brushless motor driver). I now want to make it EMI-free and followed the design guidelines in TI's Design 4: EMI Design Tips from TI Precision Labs for motor drivers.
In the EMI design guide, they suggest adding a common-mode choke and a Pi filter for noise filtering. Could you please recommend the cut-off frequencies for the common-mode choke and the inductor value for the Pi filter?
