That means when mosfet igbt is used in high.

High side switching mosfet.

3 3v is too little 24v is too much and i don t have room for a. For an n channel mosfet the source connects to ground and the drain connects to the negative side of the load. A high side p channel mosfet and a low side n channel mosfet tied with common drains figure 5 make a superb high current ªcmos equivalentº switch. I researched into high side or low side ic mosfet gate drivers but it seems that most of them do not clamp the output voltage.

For driving the mosfet in high side configuration ir2110 gate driver ic was used. N channel p channel 15. While you can use a jfet for this circuit an enhancement mode mosfet works better. In this instance the mosfet switch is connected between the load and the positive supply rail high side switching as we do with pnp transistors.

This transistor connects between v and the load. One fault common to such circuits has been the excessive crossover current during switching that may occur if the gate drive allows both mosfets to be on simultaneously. In a p channel device the conventional flow of drain current is in the negative direction so a negative gate source voltage is applied to switch the transistor on. The opposite of the low side switch is the high side switch.

A gate driver is a specially designed circuit that is used to drive the gate of mosfet or igbt in high side switching application.
