Part Number:DRV8701
My DRV8701 is signalling FAULT, with 3-ms retries, and does not seem to be the high side since when I connect IDRIVE to AVDD (disabling the high side overcurrent protection).
Can it be triggered by something else than the low side OCP? My problem seems to be sensitive to FET selection, as I have one FET version giving me this problem, and none of the other FETs do. The recommendation for gate capacitance and max switching frequency have been obeyed, as far as I can tell.
I need someone to discuss with, with some insight into the DRV8701 part.
