CAN tranceiver IC with 5000Vrms isolation and operates at 125 Deg C

Analog Devices, Inc. (ADI), has launched signal-only isolated CAN (controller area network) transceiver to provide an isolation rating of 5 kV rms and operates up to temperature of 125 Deg C. This device is offered to reduce external components and save board space. ADI claims this device reduce PCB component count by as much as 70 percent compared to traditional discrete, optocoupler based component circuits and reduces board space by up to 61 percent.

The iCoupler digital isolator technology based ADM3054 fully complies with the ISO 11898 CAN standard. This IC 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 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.Product Sample Availability Full Production Price Each Per 1,000 Packaging
