Hi, I am having problems driving a mosfet on our project. Originally I had a LVD circuit that uses a 555 timer as a Bistable Latch, The output drives a 3v relay via Pin3 and 5v. this in turn drives a 10amp relay. this all works perfectly well. However I would like to upgrade to using a Mosfet. I had copied this circuit from a similar thing on the net. I am using a logic level mosfet BUK964R4-40B,118, this is being driven by a FOD3180. The problem is that when power is applied the 555 and the FOD3180 get very hot, and the Mosfet does not switch. (when I replace the FOD3180 with a 3v relay the Mosfet works perfectly). I have obviously done something wrong and my skill level in electronics is very limited so I was hoping that someone could help me with this. Thank you, Colin
