DEMO MANUAL DC2617A

DESCRIPTION

LTC6820

isoSPI/Isolated CAN

Arduino Shield

Demonstration circuit 2617A implements the isoSPI and

isolated CAN interface hardware on a single Arduino

shield. It allows Arduino-compatible controller boards to

communicate with isoSPI and/or CAN bus networks.

DC2617A is compatible with both 5V or 3.3V logic con-

troller boards. DC2617A derives its power directly from

the Arduino controller board via the 3.3V output.

isoSPI is a robust 2-wire isolated interface popularized

by Analog Device’s family of high voltage battery stack

monitors. DC2617A includes the LTC®6820 and associ-

ated transformers to translate between the Arduino’s SPI

port and the RJ45 isoSPI connector.

CAN bus is a robust standards-based communications

method used in automotive and industrial settings.

DC2617A includes the LTM2889 isolated CAN transceiver

to connect to a CAN bus on the standard 9-pin sub-D

connector. An onboard controller (MCP2515) provides

the logic interface between the Arduino’s SPI and CAN.

Alternatively, DC2617A can be connected directly to con-

troller boards which include CAN functionality.
