New optocouplers from Avago in SO6 package
40% smaller than DIP
Avago Technologies says its new ACPL-P34x and ACPL-W34x
optocoupler family is based on process technology that enables
higher output current drive with rail-to-rail capability,
providing high-voltage insulation and robust protection
for industrial drive, inverter and power supply applications.
The optocouplers are available in a stretched SO6 package
that is 40 to 50 percent smaller than industry-standard
Dual-inline (DIP) package. With output current up to 4A
- the market's highest in this package - the family provides
reliable, fast and efficient system performance, claims
Avago.
Traditionally, Avago gate drive optocouplers have used
bipolar transistors for the output stage to deliver high
output current. With process technology improvements, the
output stage can now be replaced with bipolar CMOS/DMOS
technology, which combines the high component density and
low power consumption of CMOS with the high current drive
and speed of bipolar process. The switching speed is also
now twice as fast as the previous generation, reducing the
dead time when both the high-side and low-side transistors
are off from 700 ns to 200 ns for improved system efficiency.
"Avago continues to bring value to customers by setting
new standards for optocoupler performance, as exemplified
by our new gate drive family," said Kheng-Jam Lee,
marketing director for optocoupler products at Avago. "This
innovative family expands our optocoupler portfolio, which
is already the industry's broadest, to better address a
wider range of applications. This is especially important
for motor drive and emerging renewable energy inverter applications,
which are seeing tremendous growth in the use of IGBT."
The ACPL-P343/W343, ACPL-P341/W341 and ACPL-P340/W340 optocouplers
come in 4A, 3A and 1A maximum peak output current, respectively.
The wide range of output current allows the family to address
systems with different power ratings, including Insulated
Gate Bipolar Transistor (IGBT) and MOSFET gate drive, industrial
inverters, renewable energy inverters, AC and brushless
DC motor drives, switching power supplies, induction cookers
and inverters for home appliances. The high common mode
rejection (CMR) of the optocouplers, at 35 kV/µs prevents
erroneous driving of an IGBT and ensures reliable operation
in noisy environments. The family's stretched SO6 packages
are compliant to many industrial safety standards, including
IEC/EN/DIN EN 60747-5-2, UL 1577 and CSA.
