I gotta swap them and that kind of rework takes a long time because the drivers have a center pad connected to a ground plane... What I can tell you is that the gate voltage is in fact 15V higher than the motor voltage on the high side FETs, which tells me that the bootstrap cap is correct thus far. The problem I think I'm having is that the driver can only source 4A peak, and I'm seeing that I might need 5-7A peak... | |
