Description
The FOD8321 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 Fairchildâs 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.
