Ok, so i have a picaxe microcontroller putting out a pwm signal to the gate of an irlb3034 "logic level" n-channel mosfet.
The mosfet is for grounding on and off about 8v of 20 to 40 amps.
When i take my circuit and jump 8v directly to the gate of my mosfet everything works perfectly and the circuit works great. But when i use the digital 5v signal (even at 25% duty cycle) from my picaxe the mosfet transistor gets VERY HOT and i have already blown a few of them although i do read the pwm signal on my scope from the load which means it is technically working.
Any ideas??
