描述 Description

The FOD8320 is a 2.5A Output Current Gate Drive Optocoupler, capable of driving medium power IGBT/MOSFETs. It is ideally suited for fast switching driving of power IGBT and MOSFETs used in motor control inverter applications, and high performance power systems.

It utilizes Fairchild’s coplanar packaging technology, Optoplanar?, and optimized IC design to achieve reliably high insulation voltage and high noise immunity.

It consists of a aluminum gallium arsenide (AlGaAs) light emitting diode optically coupled to an integrated circuit with a high-speed driver for push-pull MOSFET output stage. The device is housed in a wide body 5-pin small outline plastic package.
