Automotive CAN Transceivers

Automotive CAN Transceivers

This document provides application information for the transceiver TLE7250X from Infineon Technologies AG as Physical Medium Attachment within a Controller Area Network (CAN).

The CAN protocol uses a lossless bit-wise arbitration method of conflict resolution. This requires all CAN nodes to be synchronized. The complexity of the network can range from a point-to-point connection up to hundreds of nodes.

The transceiver TLE7250X represents the physical medium attachment, interfacing the CAN protocol controller to the CAN transmission medium. The transmit data stream of the protocol controller at the TxD input is converted by the CAN transceiver into a bus signal. The receiver of the TLE7250X detects the data stream on the CAN bus and transmits it via the RxD pin to the protocol controller.
