Analog Devices Introduces Industry’s First
Fully Isolated Industrial
CAN Transceivers
- ADM3052 and ADM3053 isolated CAN transceivers are first integrated
devices to isolate signals and
power, reducing component count
by up to 80 percent and board space by up to 70 percent.
functions
in single chip, achieving significant BOM savings and breakthrough radio
performance.
NORWOOD, Mass.--( BUSINESS
WIRE)-- Analog Devices,
Inc. (ADI), a global leader in high-performance semiconductors for
signal-processing applications, has expanded its industry-leading isolated
interface product portfolio with two transceivers that are the first
to isolate both data signals and power for systems using the CAN (control-area
network) communications bus. The
ADM3052 and
ADM3053 use ADI’s
iCoupler digital isolation technology; the ADM3053 also includes
an
isoPower integrated, isolated dc-to-dc converter, reducing component
count by up to 80 percent compared to competing alternatives that require
multiple discrete devices, and consuming 70 percent less board space
than discrete competitive options.

“CAN was originally developed for the automotive
industry, but has become widely adopted in industrial and instrumentation
systems, including factory automation, building controls, wind turbines,
and elevators, in which communication with and management of multiple
sub-systems is essential,” said Mike Britchfield, vice president, Industrial
and Instrumentation Group, Analog Devices. “Targeted specifically for
the industrial and instrumentation market, the ADM3052 and ADM3053 are
the first transceivers to combine signal and power isolation in a single
device for Devicenet, CANOpen, and other CAN-based communications applications.”
The ADM3052 and ADM3053 extend ADI’s portfolio of isolated bus
communication products that includes similar products for other popular
industrial and instrumentation protocols, including RS-485/422, RS-232,
USB (universal serial bus) and I2C. These isolated communication products
integrate ADI’s transceiver devices with iCoupler digital isolation
technology and isoPower integrated, isolated dc-to-dc converters and
have already helped simplify customer product designs by integrating
signal and power isolation into single, small-form-factor packages.
Extending this same level of integration to the CAN-bus standard, the
ADM3052 and ADM3053 transceivers deliver the reliability, performance,
and control required by today’s sophisticated industrial equipment and
at the same time reduce design complexity and help customers accelerate
their time to market.

About the ADM3052
and ADM3053 CAN Transceivers
The ADM3052 CAN transceiver
offers 5-kVrms isolation between a 4-wire CAN-bus configuration and
a precision analog microcontroller or DSP (digital signal processor),
while providing the physical layer properties required by the CAN-bus
specification. The 4-wire CAN-bus configuration includes two data lines,
24-V power supply, and the power supply current return path. The ADM3052
integrates a 24-V LDO (low-dropout regulator), three channels of ADI’s
iCoupler digital signal isolation technology and the physical layer
CAN transceiver. The ADM3052 also integrates protection against wiring
faults, and a bus power-sense function, which provides an isolated signal
to the precision analog microcontroller or DSP to indicate whether the
24-V bus power supply is present or not.
The ADM3053 CAN transceiver
provides 2.5-kVrms isolation between a 2-wire CAN-bus configuration
and a precision analog microcontroller or DSP. The 2-wire CAN-bus configuration
includes only the two data lines, with bus-side power provided by ADI’s
proprietary isoPower® dc-to-dc converter technology from the precision
analog microcontroller or DSP side of the isolation barrier. The ADM3053
includes an oscillator, rectifier, regulator, two channels of iCoupler
digital signal isolation technology and the physical CAN transceiver
with integrated wire-fault protection.
The ADM3052 and ADM3053
CAN transceivers are pending safety and regulatory isolation standards
certification by UL (Underwriters Laboratories) and VDE (Verband der
Elektrotechnik). The products are available in small, surface-mountable,
wide-body SOIC (small-outline integrated circuit) packages. The wide-body
SOIC package allows the use of standard pick-and-place manufacturing
equipment and provides excellent performance in high vibration environments.
Additionally, the 0.2-mm minimum clearance above the PCB helps ensure
that isolation clearance requirements are met in high-impurity industrial
environments.

iCoupler Digital Isolation Technology
With
more than 350 million channels deployed, ADI’s proven iCoupler technology
is based on chipscale transformers, rather than on the LEDs and photodiodes
found in optocouplers. Transformers support higher data rates, consume
less power, and are more stable over life as compared to LEDs and photodiodes.
By fabricating the transformers directly on-chip using wafer-level processing,
iCoupler channels can be integrated with each other and other semiconductor
functions at low cost. iCoupler transformers are planar structures formed
from CMOS and gold metal layers. A high breakdown polyimide layer underneath
the gold layer insulates the top transformer coil from the bottom resulting
in the most reliable and highest level of digital isolation available.
CMOS circuits connected to the top coil and bottom coil provide the
interface between each transformer and its external signals.
isoPower DC-to-DC Converter Technology
ADI’s
isoPower dc-to-dc converter uses the same chip-scale transformer technology,
but instead of transmitting data, the isoPower feature employs switches,
rectifiers, and regulators to generate power that is isolated to the
same degree as the data channels. For more on ADI’s technique for isolating
power, please visit:
www.analog.com/icoupler.
The on-board isoPower isolated dc-to-dc converter can provide up to
500 mW of regulated, isolated power and can operate at either 5.0 V
or 3.3 V.
