MOSFET gate driver
International Rectifier

International Rectifier's MOSFET and IGBT gate driver ICs are the simplest, smallest and lowest cost solution to drive MOSFETs or IGBTs up to 1200V in applications up to 12kW, and can save over 30% in part count in a 50% smaller PCB area compared to a discrete opto-coupler or transformer based solution. With the addition of few external components, IR gate driver ICs provide full driver capability with extremely fast switching speeds, designed-in ruggedness and low-power dissipation.

Gate driver IC's generate the current and voltage necessary to turn MOSFETs or IGBTs on and off from the logic output of a DSP, micro-controller or other logic device. The input is typically a 3.3 volt logic-level signal. All IR gate driver ICs are CMOS compatible, and most are TTL compatible. Output currents are up to 2A.
