Reference design for I2C range extension: I2C to CAN

Description

This reference design focuses on extending I2C range from on-board to off-board through transmission cables using CAN transceivers and then converting the signal back to I2C. This approach allows for better signal integrity due to the differential signaling of the CAN transceivers. The differential signals allow for better EMI rejection: lower power: less concern of different ground potentials between boards: and the capability to use termination compared to extending the I2C lines using solely I2C buffers.

Features
  • Bidirectional CommunicationI/O Voltage Range Supports 3.3V to 5V100 kHz I2C frequency supportBus Fault Protection: +/-58 V (non-H variants) and +/-70V (H variants)Thermal Shutdown ProtectionSupports common-mode shifts up to +/-30 V without loss of function: allowing for communication between systems using different ground references
