ANALOG DEVICES ENHANCES SIGNAL ISOLATION WITH INDUSTRY’S FIRST 5-KV RMS SIGNAL-ONLY ISOLATED CAN TRANSCEIVER RATED TO 125˚C

Norwood, MA (12/14/2011) - NORWOOD, Mass. — 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 the first signal-only isolated CAN (controller area network) transceiver to provide an isolation rating to 5 kV rms with 125˚C operation. The fully certified ADM3054 offers isolated power-detect functionality in a highly integrated single surface mount package capable of operating in harsh industrial applications. By reducing PCB component count by as much as 70 percent compared to traditional discrete, optocoupler based component circuits, the new CAN transceiver greatly simplifies design while reducing board space by up to 61 percent.

More About the ADM3054 CAN Transceiver

The ADM3054 is a 5 kV rms signal-isolated CAN physical layer transceiver that fully complies with the ISO 11898 CAN standard. The new CAN transceiver leverages Analog Devices’ highly regarded iCoupler® digital isolator technology and combines a 3-channel digital isolator with a CAN transceiver in a 10 mm x 10 mm single-surface-mount, 16-lead, wide-body SOIC (small-outline IC) package.

The ADM3054 complements ADI’s previously released isolated CAN products, the ADM3052 and ADM3053, which provide power isolation in addition to signal isolation. The ADM3054 is targeted at applications where an isolated power rail already exists or an additional overwind from an existing isolation transformer can be used. The device’s logic is powered with a single 3.3-V or 5-V supply on VDD1 while the bus side uses a single 5-V supply on VDD2 only. Loss of power on the bus side (VDD2) can be detected by the mico-controller using the integrated VDD2SENSE signal. The transceiver has integrated +/-36V fault protection on the bus pins, CANH and CANL, to guard against shorts to power/ground in 12- V and 24-V systems. The device also has current-limiting and thermal-shutdown features that protect against output short circuits and situations where the bus might be shorted to ground or power terminals.

The ADM3054 creates an isolated interface between the CAN protocol controller and the physical layer bus. It is capable of running at data rates of up to 1 Mbps and is fully specified over the industrial temperature range of −40˚C to +125˚C.
