hi,
i'm makind stepper drive circuit using an IRFZ44N mosfet.the connections i made are shown.i gave 12V from an SMPS having a max current of 23A.even though the gate was zero,i measured a current of 2.2A in the drain-source.the mosfet was very hot(really hot).(i connected the multimeter in between V+ and pin of the mosfet).please correct the circuit if there are any problems.i want V+ as 12V.
the rating Vdss is 55V.i assumed it is the max voltage across D&S.please verify.
thank you
