Avago Technologies Announces Industry's First Wide Temperature Digital Optocouplers for Industrial Applications

New Optocouplers Meet Temperature and Low Power Requirements of
Industrial Inverter and Power Management Manufacturers
SAN JOSE, Calif.--(Business Wire)--Avago Technologies today announced the addition of three new
high-temperature, high-speed digital optocouplers which are the first
in the industry for use in industrial applications. These new wide
temperature optocouplers, which are housed in a 5-pin surface mount
package, have been designed to operate over a wide range of
temperatures from -40 to 125-degrees C making them extremely reliable
and ideal for use in applications that operate in harsh industrial
environments. Today's announcement will enable Avago to provide its
industrial customers with wide temperature optocoupler products in
speeds ranging from one megabaud (1 MBd) to 10 MBd. Avago is a leading
supplier of analog interface components for communications, industrial
and consumer applications.

These latest additions to Avago's optocoupler family include a 1
MBd single channel digital optocoupler (ACPL-M43U), a 10 MBd logic
gate optocoupler (ACPL-M61U), and an intelligent power module
optocoupler that includes an aluminum gallium arsenide (AlGaAs) layer
optically coupled to an integrated high gain photo detector
(ACPL-M46U). These new high-speed digital optocouplers are low-power
and high common mode transient rate (CMR) components that provide
immunity to transient noises, EMI and ground loop eliminations.
Avago's ACPL-M43U, M46U and M61U optocouplers are compliant to most
industrial safety standards such as IEC/EN/DIN EN 60747-5-2, UL 1577
and CSA.

The trend in the industrial market is moving towards components
that can operate in high temperatures as systems become more
sophisticated and integrated in the harsh operating environments found
in industrial applications. With the growing number of electrical
components being embedded into industrial applications, isolation
plays a key role in the optimal performance, as well as the electrical
safety and integrity of industrial equipment.

The SO-5 JEDEC registered (MO-155) package outline offers
space-savings in the printed circuit board (PCB) and has a footprint
that is approximately one-fourth the area of a standard dual-in-line
package. The lead profile is designed to be compatible with standard
surface mount processes.

The difference between the ACPL-M43U and M46U is that the M46U
offers excellent propagation delay difference that allows the circuit
designer to reduce switching dead time to improve inverter efficiency.
These extended temperature IPM optocouplers are ideal for use in
battery management systems, motor control, isolated IGBT/MOSFET gate
drives, AC and brushless DC motors, and industrial inverters for power
supplies.

Avago's ACPL-M61U 10 MBd optocoupler, targets industrial
communications interface applications. Its optically coupled gates
combined with a AlGaAs light emitting diode and integrated high gain
photo detector, are ideal for use with most industrial communication
interfaces (such as RS232, RS485, CANBus etc), high temperature
digital signal isolation, microcontroller interfaces, and digital
isolation for A/D and D/A conversion.

Key Features

-- High temperature reliable IPM driver and CANBus communication
interface for industrial applications

-- Wide temperature range: -40 to 125-degrees C

-- Very high common mode rejection min 10kV/(mu)s at VCM = 1500V
(VCM = 1000V for ACPL-M61U)

-- Compact, auto insertable SO5 packages

-- RoHS compliant

Pricing and Availability

Avago's ACPL-M43U, M46U and M61U optocouplers are priced at $1.50,
$1.63 and $1.75 respectively in 10,000 quantities. Samples and
production quantities are available now through Avago's direct sales
channel and worldwide distribution partners.
