Guys
I'm trying to control a heater using MCU and MOSFET. my MCU is an STM32 and is operating at 3v3 and my mosfet is F9530N. here is the circuit:
When I connect 24v to the 24v terminal, the MOSFET starts to get so hot as it's about to melt its solder while MCU pin is 0v and the gate voltage is 12v5. Why it's getting hot?
Edit: It apears that the MOSFET is conduncting because the heater starts to get hot.
