N Channel Mosfet High Side Switch

Can you have an n channel mosfet in the high side of the circuit.

N channel mosfet high side switch.

This transistor connects between v and the load. The opposite of the low side switch is the high side switch. Used as a high side switch a p channel mosfet in a totem pole arrangement with an n channel mosfet will simulate a high current high power cmos complementary mos arrangement. One huge advantage in using n channel mosfets as opposed to p channel mosfets is that the conduction losses are much lower for similarly priced devices.

N channel mosfets can also switch v in certain configurations with drain being vin and source being switched vout. The n channel high side switch. Another disadvantage of p channel mosfets is the much. 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.

Yes but there are issues. While you can use a jfet for this circuit an enhancement mode mosfet works better. N channel mosfets have lower on resistances than p channel mosfets so are preferable if you have the choice of which side to 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.

In order to do this the gate voltage must be magnified in some way. The max1614 drives high side n channel power mosfets to provide battery power switching functions in portable equipment. Use a p channel mosfet with source connected to v.
