Description
The HCPL-314J 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.

Applications Information
Eliminating Negative IGBT
Gate Drive
To keep the IGBT firmly off,
the HCPL-314J has a very low
maximum VOL specification of
1.0 V. Minimizing Rg and
the lead inductance from the
HCPL-314J to the IGBT gate and
emitter (possibly by mounting the
HCPL-314J on a small PC board
directly above the IGBT) can
eliminate the need for negative
IGBT gate drive in many
applications as shown in
Figure 19. Care should be taken
with such a PC board design to
avoid routing the IGBT collector
or emitter traces close to the
HCPL-314J input as this can
result in unwanted coupling of
transient signals into the input of
HCPL-314J and degrade
performance. (If the IGBT
drain must be routed near the
HCPL-314J input, then the LED
should be reverse biased when in
the off state, to prevent the
transient signals coupled from
the IGBT drain from turning on
the HCPL-314J.)
