Hi,
I think there might be a typo in TIDA-00901 schematic, page 2. The power input is 20 A. Thus, each phase current of the motor should be 20 A/sqrt(3) = 12 A. But the schematic marked 20 A on MOT_A, MOT_B, and MOT_C. Please confirm whether they are typos.
Thanks and I look forward to hearing from you,
John
