Fundamentals of mosfet and igbt gate driver circuits the popularity and proliferation of mosfet technology for digital and power applications is driven by two of their major advantages over the bipolar junction transistors.

A mosfet driver is a type of power amplifier that accepts a lowpower input from a controller ic and produces a highcurrent drive input for the gate of a highpower transistor such as an insulated gate bipolar transistor igbt or power mosfet. Mosfet drivers are beneficial to mosfet operation because the highcurrent drive provided to the mosfet gate decreases the switching time between the. The input is cmos compatible, and is virtually immune to latch up. Pdf design of highside mosfet driver using discrete. One of these benefits is the ease of use of the mosfet devices in high frequency switching applications. A gate driver is used when a pulsewidthmodulation pwm controller cannot provide the output current required to drive the gate capacitance of the associated mosfet.
