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.
