FOD8320
High Noise Immunity, 2.5A Output Current, Gate Drive
Optocoupler in Optoplanar® Wide Body SOP 5-Pin
Features
Description
®
■ Fairchild’s Optoplanar packaging technology
provides reliable and high voltage insulation with
greater than 10mm creepage and clearance distance,
and 0.5mm internal insulation distance while still
offering a compact footprint
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.
■ 2.5A output current driving capability for medium
power IGBT/MOSFET
It utilizes Fairchild’s coplanar packaging technology,
Optoplanar , and optimized IC design to achieve reliably
high insulation voltage and high noise immunity.
®
– Use of P-Channel MOSFETs at output stage
enables output voltage swing close to the supply
rail
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.
