TIDA-020019 Reference Design

Texas Instruments

Automotive isolated CAN and power front end reference design

Description

This reference design demonstrates reinforced isolated CAN communication: which is widely used in automotive environments: in a small footprint. In hybrid and electric vehicles (HEV/EVs): a complete 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. This TI design has a low transmission delay: which reduces the loop delay and supports higher baud rates of the CAN.

Features
  • Integrated CAN and digital isolator (ISO1042-Q1)Low loop delay (typically 139 ηs) to support high-speed arbitration ratesInbuilt reinforced digital isolation±70-V bus fault protectionCompliant with ISO 11898-2 CAN standard
Applications
  • Flight control system
  • Aircraft engine control/monitoring
