Polarity Correcting Isolated CAN Reference Design

TIDA-00267

Design files

Overview

A ready to use design that efficiently solves the problem of improper installation by adding antiparallel communication channels and appropriate control signal to enable polarity correction for the Controller Area Network (CAN) bus.

Features
  • Simplifies system installation with use of one control signal to enable polarity correction in case of cross wire fault
  • Discrete isolation enables tailored upgradability with other 16-pin SOIC DW packaged parts
  • Custom isolated power creates high efficiency solution
  • Turbo CAN Transceiver with fast loop times for large networks or fast data-rates
  • ISO7842 - 5.7 KVRMS isolation rating

A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
