Description
The HCPL-J314 family of devices
consists of an AlGaAs LED
optically coupled to an integrated
circuit with a power output stage.
These optocouplers are 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 small
or medium power IGBTs. For
IGBTs with higher ratings the
HCPL-3150(0.5A) or HCPL-3120
(2.0A) optocouplers can be used.
