DESCRIPTION
The VO3120 consists of a 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
voltage and current supplied by this optocoupler makes it
ideally suited for directly driving IGBTs with ratings up to
800 V/50 A. For IGBTs with higher ratings, the VO3120 can
be used to drive a discrete power stage which drives the
IGBT gate.
