High Side P Channel Mosfet Driver Circuit

Yes but there are issues.

High side p channel mosfet driver circuit.

Mps high frequency half bridge n channel power mosfet drivers with up to 100v vbst voltage range controll low side and high side driver channels independently with less than 5ns gate drive mismatch. 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. 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. Key features include wide input range of operation wide temperature range of operation and powerful gate drive.

This transistor connects between v and the load. For an n channel mosfet the source connects to ground and the drain connects to the negative side of the load. Analog devices growing portfolio of high side switches and mosfet fet drivers provides a simple and effective solution to drive single dual triple or quad n channel or p channel fets. 20 level shifted p channel mosfet driver.

A new requirement is that the circuit is turned on and off on the high side. 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. Procedure for ground referenced and high side gate drive circuits ac coupled and transformer isolated solutions are described in great details. 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.

3 3v is too little 24v is too much and i don t have room for a. Key features include wide input range of operation extended temperature range of operation a powerful gate drive and short circuit protection. A special section deals with the gate drive requirements of the. A single p channel mosfet configured to the high side seems like it is on the right track but requires that the pin be set high to turn off the circuit so that won t work to keep the current usage to near zero when in deep sleep.

There are a variety of configurations for driving the two mosfets with many different applications. While you can use a jfet for this circuit an enhancement mode mosfet works better.
