Could be very simple, but you need to specify the current demand (including startup and stall current) of your motor.I want to use my microcontroller pwm output to drive a power dc motor of 12vdc .I want to use irfz44n mosfet.just the circuit is to be able to increase or decrease the motor speed nothing else.So what configuration to implement.
I believe this should do.So what would be a better and cheap option to drive those mosfets(irfz44n)
Yes, my rise time on the gate will be pathetically slow. Thanks for correcting me. I like your circuit as it mimics TTL.That'll turn off pretty quickly, but the 10k resistor in the gate charge path will cause a very slow turn-on time, and much power dissipation in the MOSFET.
