Infineon TLE9255WLCXUMA1: High-Speed CAN Transceiver for Automotive Networks

The evolution of automotive electronics demands robust, reliable, and high-performance communication networks. At the heart of these advanced in-vehicle networks (IVNs) lies the Controller Area Network (CAN) bus, a cornerstone for real-time data exchange between electronic control units (ECUs). The Infineon TLE9255WLCXUMA1 emerges as a premier solution, a highly integrated high-speed CAN transceiver designed to meet the stringent requirements of modern automotive applications.

This transceiver serves as the critical interface between the protocol controller and the physical CAN bus. It is engineered to handle the challenging conditions of the automotive environment, offering exceptional electromagnetic compatibility (EMC) and low electromagnetic emission (EME), which are paramount for minimizing interference with sensitive electronic systems. The device supports CAN FD (Flexible Data-Rate), enabling faster data throughput compared to classical CAN, which is essential for the increasing data volumes from sensors, cameras, and advanced driver-assistance systems (ADAS).

A key feature of the TLE9255WLCXUMA1 is its robustness against electrical hazards. It provides excellent electrostatic discharge (ESD) protection and is resilient to transients typical in automotive power systems, such as load dump and jump-start events. Furthermore, it offers comprehensive diagnostic capabilities, including thermal shutdown, undervoltage detection, and bus failure recognition, enhancing system-level safety and reliability—a critical aspect for functional safety standards like ISO 26262.

Housed in a compact, green SG-TSON-14 package, the device is optimized for space-constrained applications. Its low-power management features, including a standby and sleep mode with local and remote wake-up functionality, make it ideal for always-on systems that require minimal quiescent current to support start-stop functionality and extend battery life.

In summary, the Infineon TLE9255WLCXUMA1 is a state-of-the-art transceiver that ensures secure, high-speed, and dependable data communication across the automotive network, paving the way for more connected and autonomous vehicles.
