DESCRIPTION
The VOFD343A consists of a AlGaAs LED optically coupled
to an integrated circuit with a power output stage. This
optocoupler is ideally suited for driving power IGBTs
and MOSFETs used in motor control inverter applications.
The high operating voltage range of the output stage
provides the drive voltages required by gate controlled
devices. The VOFD343A is ideally suited for directly driving
IGBTs with ratings up to 1200 V / 100 A. For IGBTs with
higher ratings, the VOFD343A can be used to drive a
discrete power stage which drives the IGBT gate. FEATURES
