Let’s say you’ll use an N-Channel MOSFET (IRF520) as a switch with your Arduino board to control some random load device (LED, Motor, or Heater). Here’s how to set it up and drive the MOSFET’s gate using a discrete BJT-based circuit.
Using MOSFETs As General Switches – IBEX Resources
Use a N-Channel MOSFET with Source connected to 0V (either directly or via a current limiting resistor) and the load connected to Drain. Whenever the Gate voltage exceeds the Source voltage by at least the Gate Threshold Voltage the MOSFET conducts. The higher the voltage, the more the Mosfet can conduct.
N-Channel MOSFET High-Side Drive: When, Why and How?
2013年2月24日 · Fig. 2 - N-channel MOSFET configured as high-side switch. You can quite easily see the difference between the high-side configuration and the low-side configuration. In the low-side configuration, the load is connected between the drain and +V, while the source is connected to ground. Thus, the gate drive is referenced to ground.
