HCPL-3020/ 0302
0.2 A Output Current Gate Drive Optocoupler
from Agilent Technologies
The HCPL-3020 in DIP-8 and
HCPL-0302 in SO-8 package
complement Agilent鈥檚
existing family of gate drive
optocouplers. The new 0.2 A
devices consist of GaAsP
LEDs optically coupled to
an integrated circuit with
a power output stage. The
current rating, combined
with the high common
mode rejection (CMR),
fast switching and latch-
up performance uniquely
qualify these optocouplers
for low-power inverter gate
drive applications. The high
operating voltage ranges of
the HCPL-3020 and HCPL-
0302 output stages provide
the drive voltages required
by MOS-gated devices like
IGBTs or MOSFETs. The
voltage and current provided
by these optocouplers make
it suitable for driving IGBTs
with rating up to 1200 V/
20 A. For IGBTs with higher
ratings, the HCPL-0314/3140
(0.4 A), HCPL-3150 (0.5 A) or
HCPL-3120 (2 A) can be used.
The HCPL-3020 and HCPL-
0302 are among the cheapest
solutions available for
driving MOS-gated devices in
a safe, ef鏗乧ient, reliable and
cost-effective way. Besides
ease of implementation,
the HCPL-3020 and HCPL-
0302 also excel in power
consumption. The low supply
current of 3 mA allows
bootstrap techniques, thus
eliminating additional
isolated power supplies for
gate drive circuitry. Using
discrete power IGBTs or
MOSFETs together with gate
drive optoisolators instead
of integrated modules
allows the designer to
control the gate signal 鏗俹w.
This makes it possible to
change the switching speed
and related EMI behavior.
Compared with high-voltage
integrated circuits (HVICs)
Agilent鈥檚 optocouplers offer
superior galvanic isolation.
The optoisolators feature a
proprietary internal Faraday
shield, which provides the
best common-mode rejection
(CMR) performance of any
competing isolation solution.
