I need some help, I am blowing my inverting mosfet driver.
The circuit is a motor driver to run a 12v motor.
uno32 - H11L1 opto coupler - tc4429 mosfet driver - irlb3034. - 30amp dc motor
My problem is that the tc4429 chip keeps breaking, first it gets hot but still works and eventually stops working at all.
When looking at the signals with a oscilloscope i see what looks line a sine wave the distance between peaks is about 5mV
I suspect that the might be the fact that the battery powering the circuit is not connected well enough. I will test tomorrow to check. But I would like ideas what else the issue could be.
Link to the circuit.
