Key Document


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.

  • Integrated CAN and digital isolator (ISO1042-Q1)
  • Low loop delay (typically 139 ηs) to support high-speed arbitration rates
  • Inbuilt reinforced digital isolation
  • ±70-V bus fault protection
  • Compliant with ISO 11898-2 CAN standard
