Data Sheet
Description
The HCPL-3140/HCPL-0314 family of devices consists
of a GaAsP LED optically coupled to an integrated
circuit with a power output stage. These opto-
couplers 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 (0.5 A) or
HCPL-3120 (2.0 A) opto-couplers can be used.
A 0.1 µF bypass capacitor must be
connected between pins V

and V
