MOSFET driver external circuit

Using Arduino General Electronics

Hi All,

Thank you for your replies.
I think there is some misunderstanding over here. I remember I mentioned that I used a driver with +/- 9A peak current capacity (UCC37322P). I used several different gate resistor values on this one:

  • no gate resistor, and it blew up with not even a load attached to the mosfet (same mosfet).
  • 100 Ohm resistor, it worked with no load, but was fireball with 30A load
  • 220 Ohm resistor, it worked with 30A load, but explosion with 60A load
  • 470 Ohm resistor, works with 30A load, but explosion with 60A load

Now I am using this beefier driver IXDD614CI with +/- 14A peak current, and +/- 4A continuous. I tried it with 470 Ohm gate resistor and 60A load. No explosion or fire, but it failed (latched on).
I need a gate resistor in place of the 470 Ohm (higher or lower, I dont care) that can handle the high 60A current through the MOSFET.
I have attached a PDF schematic of what I am doing.

Thanks.
