WebWhen the output of the PIC is HIGH, the transistor is turned ON and pulls the gate of the MOSFET LOW. This turns the MOSFET ON and current will flow through the load. N CHANNEL MOSFET. (Load connected between Drain and +12V) When the PIC output is LOW, the transistor is OFF and the gate of the N MOSFET is HIGH (12V). WebThe MOSFET conducts current between its source and drain through a path called a channel. The width of this channel is controlled by the voltage at the gate terminal. MOSFET is a voltage-controlled device whose output depends on the gate voltage. The metal oxide gate is electrically isolated from the channel using a thin layer of silicon dioxide.
