I had worked on some mosfets last year. Cannot remember the exact model no.
Now i planning to use Mosfets in some LED driver circuit. The Mosfet im planing to use is the IRFZ44N. It states that the Vgs(threshold) is 4.0V.
Does this mean in can directly interface it with my AVR logic outputs. Or do i require a mosfet driver. I remember last year i had made a driver wherin the gate voltage was above 8volts for a valid logic high.
