I've been using this MC2100 in conjunction with a pwm circuit I built, and had been using it successfully for a time on a bandsaw. I must have pushed it a little too hard when resawing a log, as the motor suddenly stopped in the middle of the cut. The behavior afterward was that turning it on resulted in the motor ramping up to full speed and then stopping. Looking around on this forum it seemed like I blew out the mosfet, Q4 on my board, and I checked it and it was shorted. I replaced that, but I still get the same behavior (on a scope the voltage output ramps up to about 100V and then slowly decays).
Not sure what to look for now, nothing else seems to be shorted on the board. The LED blinks twice then pauses, which according to this video indicates a wire has become disconnected, which is a bit unhelpful.
Any help is appreciated.
