Thanks for your help.
Can i use 2N2222 as a driver ? is it fast enough to handle the PWM frequency ?
And the resistor will operate as a heating element in an incubator.
Hello,
I need help in choosing the right MOSFET for my circuit.
I want to connect a power resistor 50W 4ohm to 12V (from cpu power supply) with a MOSFET.
The Gate pin of the MOSFET will connect to a pwm pin of ATmega328 (pwm 490hz and 5V logic '1').
In conclusion i need to know what MOSFET...
