Automotive Reinforced Isolation CAN Reference Design

TIDA-01255

Design files

Overview

This reference design is built for isolated CAN communication, which is widely used in automotive environments. In hybrid and electric vehicles (HEV/EVs), a high-voltage network is floating with respect to the chassis ground. Isolation is required for the power and communication channels interfaced between floating high- to low-voltage systems. TIDA-01255 supports applications with a simple isolated transformer driver to transfer power. This reference design has a low-transmission delay which reduces the loop delay and supports higher baud rates of the CAN.

Features
  • Flexible high-speed CAN communication
  • Low-loop delay (typically 136 ηs) to support high-speed arbitration rates
  • 750-mW power transfer with 3-kV isolation
  • ±70-V bus fault protection
  • Compliant with ISO 11898-2 CAN standard
