Analog Devices is offering its first signal-only isolated CAN transceiver to provide an isolation rating to 5kVrms with 125˚C operation.

The ADM3054 signal-isolated CAN physical layer transceiver that fully complies with the ISO 11898 CAN standard. 

The CAN transceiver is based on the firm's 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.

It 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 3.3V or 5V supply on VDD1 while the bus side uses a single 5V supply on VDD2 only.

Loss of power on the bus side (VDD2) can be detected by the micocontroller 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.
