N Channel Mosfet High Side Switch

Then the p channel mosfet is used to switch the positive supply to the motor for forward direction high side switching while the n channel mosfet is used to switch the negative supply to the motor for reverse direction low side switching.

N channel mosfet high side switch. This transistor connects between v and the load. In the low side configuration the load is connected between the drain and v while the source is connected to ground. While you can use a jfet for this circuit an enhancement mode mosfet works better. 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.

The opposite of the low side switch is the high side switch. The higher the voltage the more the mosfet can conduct. N channel mosfets have lower on resistances than p channel mosfets so are preferable if you have the choice of which side to switch. 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.

The main problem in using an n channel mosfet in a high side switch is that in order for the mosfet to switch off once it has been switched on is that the voltage on the gate terminal of the mosfet must be made higher than the supply voltage. N channel mosfets can also switch v in certain configurations with drain being vin and source being switched vout. There are a variety of configurations for driving the two mosfets with many different applications. The n channel high side switch.

Although the p channel mosfet cannot complement the n channel in both on resistance and capacitance simultaneously such combinations as the low threshold p channel tp0610 and the n channel 2n7000. For an n channel mosfet the source connects to ground and the drain connects to the negative side of the load. In order to do this the gate voltage must be magnified in some way.
