Description
The FOD3120 is a 2.5A Output Current Gate Drive
Optocoupler, capable of driving most 1200V/20A
IGBT/MOSFET. It is ideally 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 aluminum arsenide (AlGaAs) light
emitting diode optically coupled to an integrated circuit
with a high-speed driver for push-pull MOSFET output
stage.
