DC2617A is a LTC6820 demonstration board an 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 controller 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 associated 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.
