TIDA-01487
Isolated CAN Flexible Data (FD) Rate Repeater Reference Design
TIDA-01487
Overview
CAN and CANopen are legacy Fieldbus protocols used in many applications in factory automation. Whenever high voltage can 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 design support CAN FD speed up to 2 Mbps. The reference design is supplied by a wide-range voltage supply between 6 V to 36 V.
