The FOD3120SDV is a 2.5A output current high noise immunity Gate Drive Optocoupler, capable of driving most 800V/20A IGBT/MOSFET. It is suited for fast switching driving of power IGBT and MOSFETs used in motor control inverter applications and high performance power system. It utilizes Fairchild's proprietary coplanar packaging technology, Optoplanar? and optimized IC design to achieve high noise immunity, characterized by high common mode rejection. It consists of a gallium aluminium arsenide (AlGaAs) LED (LED) optically coupled to an integrated circuit with a high-speed driver for push-pull MOSFET output stage. Use of P-channel MOSFETs at output stage enables output voltage swing close to the supply rail.
