I want to make 12V 60watt LED dimmer by mosfet and arduino or esp32. I have a couple of IRFZ44N in my table but they are not logic level mosfets, as i know they need 10V to fully turn on. What is the possible solution to use this irfz44n at its full potential with arduino or esp32? I also have some BC547 transistors.
If you don't want to buy more parts then use the transistor to turn on the MOSFET.

That is something ChatGPT can answer well, just type the following into the prompt [How can I connect an arduino to a BC547 to a IRFZ44N] leave out the []

Ok. Should i give 10V or 12V to gate pin?
I hope you know how "high power" LED drivers and dimmers work... They normally need a constant current (or controlled current) source.
Unless you have an LED strip... They have resistors to control/limit the current so you can use a regular constant-voltage supply and PWM for dimming.
What's the max Vgs says the datasheet?
IIRC the gate voltage should be 10V.
If max Vgs is higher, anything above 10 V and under max is not a problem, except that you wanna stay away from those Absolute maximum values...
