DCAN250 - CAN over Battery
Power Line Communication
Preliminary Information
Description
The DCAN250 is a VLSI device for Multiplex CAN bus communication over battery Power Lines (PLC). It
is a complete transceiver solution for CAN bus alternative physical layer between for a wide range of
vehicular modules such as the steering wheel, doors, sensors, displays, Internet/navigation computer,
security, control panel, etc.
The device operates as a smart DC - PLC transceiver for CAN bus controllers. The DCAN250 contains a
modem, a channel coder/decoder (ECC), a communication controller, and a message-buffered host
interface to overcome the hostile environment of vehicle battery lines. A Sleep Mode reduces the power
consumption when no bus communication exists. The DCAN250 is based on the DC-BUS technology,
that reduces harness weight whilst enabling flexible, quick and simple installation.
