Description

CAN and CANopen are legacy fieldbus protocols used in many applications in factory automation. Whenever high voltage could damage the end equipment there is need for isolation. This isolated CAN flexible data (FD) rate repeater reference design adds electrical isolation between two CAN bus segments. The CAN frames on either bus segment side are repeated to the other side. The CAN transceiver and arbitration logic in this TI design support CAN FD speed up to 2Mbps. The TI design is supplied by a wide range voltage supply between 6V to 36V.

Features
  • Isolated CAN FD transceiver with 3000 VRMS isolation rating
  • Support classic CAN and 2 Mbps CAN FD
  • Single 24V industrial supply
  • Wide supply voltage range of 5V to 36V
  • Onboard generation of isolation voltages
