Hi everybody.
I need a circuit to control a high watt resistor for some purpose.I have a circuit which includes an opamp and a mosfet but in that the Vgs would be 2.5 v and thus high Rds on that would burn the mosfet.The power supply is 5 volts max and the current varies between 0 to 4 Amps.
This is my own circuit.
