Infineon TLE9255WSKXUMA2: High-Speed CAN Transceiver for Automotive Networking

The evolution of modern vehicles into complex, software-defined systems hinges on the seamless and reliable exchange of data between electronic control units (ECUs). At the heart of this robust communication lies the Controller Area Network (CAN), and its performance is critically dependent on the physical layer transceiver. The Infineon TLE9255WSKXUMA2 stands out as a premier high-speed CAN transceiver, engineered to meet the stringent demands of next-generation automotive networking.

This device is designed for high-speed CAN (CAN FD) networks, supporting flexible data rates up to 5 Mbit/s. This capability is essential for handling the increasing data volumes from advanced driver-assistance systems (ADAS), infotainment, and powertrain applications, where traditional CAN speeds are no longer sufficient. The TLE9255WSKXUMA2 ensures that data packets are transmitted and received with integrity across the vehicle's network.

A key feature of this transceiver is its enhanced electromagnetic compatibility (EMC) and electrostatic discharge (ESD) protection. Operating in the electrically harsh environment of an automobile, the device is rigorously shielded against interference and can withstand ESD events up to ±8 kV, significantly improving system reliability and reducing the risk of communication errors or hardware damage.

Furthermore, the TLE9255WSKXUMA2 boasts very low power consumption, featuring a dedicated sleep mode with a minimal current draw. This is paramount for supporting the always-on ECUs in modern vehicles without draining the battery, making it an ideal solution for applications requiring energy efficiency. Its robust design for automotive environments is confirmed by its compliance with the AEC-Q100 qualification standard, ensuring operational resilience across a wide temperature range and under demanding conditions.

The transceiver also integrates advanced diagnostic functions, including comprehensive failure mode detection such as short-circuit conditions, loss of battery, and overtemperature. This allows for proactive system monitoring and maintenance, enhancing overall vehicle safety.

Housed in a compact, surface-mountable package, it is optimized for space-constrained applications, offering manufacturers a reliable and efficient solution for building sophisticated in-vehicle networks.
