Overview

The DC2617A is an Arduino-compatible expansion board featuring the LTC6820 isoSPI-to-SPI signal translator. It allows for high-speed SPI communication over distances up to 100 meters using a single twisted pair, providing galvanic isolation for rugged battery management or industrial systems.

Why Choose This Part

It simplifies the implementation of isolated SPI by using standard RJ45 connectors and twisted-pair cabling. The board supports data rates up to 1 Mbps and operates within a 3.3V to 5V input range, making it directly compatible with most Arduino-style headers.

Applications

Battery Management Systems (BMS)
Interfacing Arduino-based controllers with remote battery monitoring ICs like the LTC6811 or LTC6813 across high-voltage isolation barriers.
Isolated Industrial Networking
Extending SPI communication between sensors and controllers in electrically noisy environments where ground loops are a concern.
Electric Vehicle Prototyping
Rapidly developing isolated communication links for powertrain sub-systems using the standard Arduino form factor.
