Yesterday during an experiment, module 6 was replaced with a new GaN module solution, and the fault was changed from module 6 to module 3. AVDD load current waveform of 1A, disabled state. Enable state Motor closed-loop control to 1A current AVDD waveform The current solution for the customer is to reset AVDD using a program after a malfunction occurs. But the customer wants to find the cause and solve the problem from the root.
