Description

The HCPL-3150 consists of a

GaAsP 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 applica-

tions. The high operating voltage

range of the output stage pro-

vides 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 1200 V/50 A.

For IGBTs with higher ratings,

the HCPL-3120 can be used to

drive a discrete power stage

which drives the IGBT gate.
