HCPL-3140/HCPL-0314
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 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 (0.5 A) or
HCPL-3120 (2.0 A) optocouplers
can be used.
