Ir2110 arduino cpde5/3/2023 ![]() ![]() When I’m writing this the Vb voltage is 14V in relation to ground but 0V in relation to Vss.īTW, using this chip in a low side circuit works fine, but in the high side there aren’t even a small signals indicating that the mosfet is getting turned on, as if the bootstrap capacitor weren’t getting charged up to the proper voltage. I’ve had several problems with this circuit, one of them being that the motor isnt turning, but also that source is actually giving the mosfet power, not from my 12v supply for the motor, but from my 14V supply that I’m using for the bootstrap. Like I already said, I’m only using 1 mosfet for the high side, I’ve grounded everything else. I’m using an 22uf tantalum capacitor for the bootstrap operation, 10ohm gate resistors and a 14V power supply for the bootstrap. I’ve rebuilt it many times so I don’t think I’ve made any basic mistakes. The problem is that the circuit is not working. So I’m using the ir2110 mosfet driver with to drive the ir3205 mosfet in a high side circuit. ![]()
