Description
The HCPL-3140/HCPL-0314
familyofdevicesconsistsofaGaAsPLED
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.
Features
• 0.4 A minimum peak output
current
• High speed response:
0.7 µs maximum propagation delay
over temperature range
• Ultra high CMR:
minimum 10 kV/µs at VCM = 1 kV
• Bootstrappable supply current:
maximum 3 mA
• Wide operating temperature
range: –40°C to 100°C
• Wide VCC operating range:
10 V to 30 V over temp. range
• Available in DIP8 and SO8
package
• Safety approvals: UL approval
pending, 2500 Vrms for 1 minute.
CSA approval pending. VDE

(HCPL-3140)
Applications
Isolated IGBT/Power MOSFET
gate drive
AC and brushless DC motor drives
Inverters for home appliances
Industrial inverters
Switch Mode Power Supplies
(SMPS)
A 0.1 µF bypass capacitor must be connected between pins VCC and VEE.
CAUTION: It is advised that normal static precautions be taken in handling and assembly of this component to prevent damage
and/or degradation which may be induced by ESD.

Applications Information
Eliminating Negative IGBT Gate
Drive
To keep the IGBT firmly off,
the HCPL-3140/HCPL-0314 has a
very low maximum VOL
specification of 1.0 V. Minimizing
Rg and the lead inductance from
the HCPL-3140/HCPL-0314 to
the IGBT gate and emitter
(possibly by mounting the
HCPL-3140/HCPL-0314 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-3140/HCPL-0314 input as
this can result in unwanted
coupling of transient signals into
the input of HCPL-3140/
HCPL-0314 and degrade
performance. (If the IGBT
drain must be routed near the
HCPL-3140/HCPL-0314 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-3140/
HCPL-0314.)
