General Description
The FOD3120 is a 2.5A Output Current Gate Drive Optocoupler, capable of driving most 800V/20A IGBT/MOSFET. It is really 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 patented coplanar packaging technology, Optoplanar®, and optimized IC design to achieve high noise immunity, characterized by high common mode rejection.
It consists of a gallium aluminum arsenide (AlGaAs) light emitting diode optically coupled to an integrated circuit with a high-speed driver for push-pull MOSFET output stage.
