Infineon TLE7258SJXUMA1 High-Speed CAN Transceiver for Automotive Networks

The evolution of modern vehicles into complex, software-defined systems has placed unprecedented demands on in-vehicle networking. At the heart of this communication infrastructure lies the Controller Area Network (CAN), and its performance is critically dependent on robust physical layer components. The Infineon TLE7258SJXUMA1 stands out as a premier high-speed CAN transceiver designed to meet the rigorous requirements of next-generation automotive applications.

This transceiver serves as the vital interface between a CAN protocol controller and the physical two-wire CAN bus. It is engineered for high-speed CAN networks operating at bit rates up to 8 Mbit/s, far exceeding the classic 1 Mbit/s limit, making it ideal for bandwidth-intensive domains like advanced driver-assistance systems (ADAS), powertrain, and chassis applications. A key feature of the TLE7258SJ is its exceptional electromagnetic compatibility (EMC) and electrostatic discharge (ESD) robustness. With ESD protection up to ±8 kV according to IEC 61000-4-2, it ensures superior resilience against electrical transients commonly encountered in the harsh automotive environment, significantly enhancing system reliability.

Furthermore, the device incorporates advanced functionality for improved network management and power saving. It features a low-power management mode with local and remote wake-up capability. This allows electronic control units (ECUs) to enter a standby mode with minimal current consumption, reducing the overall quiescent current of the vehicle's electrical system and contributing to energy efficiency, a critical factor for both conventional and electric vehicles.

The TLE7258SJ also includes comprehensive protection mechanisms and diagnostic features. It offers overtemperature and short-circuit protection on the bus outputs, safeguarding the transceiver and the broader network from potential damage due to fault conditions. Its compatibility with 3.3 V and 5 V microcontrollers provides designers with greater flexibility during system development.

In summary, the Infineon TLE7258SJXUMA1 is a cornerstone technology for building reliable, high-performance, and fault-tolerant automotive networks. Its blend of high-speed data transfer, superior robustness, and intelligent power management makes it a trusted solution for automakers and Tier 1 suppliers worldwide.

ICGOODFIND: The Infineon TLE7258SJXUMA1 is a highly robust and efficient high-speed CAN transceiver, offering best-in-class EMC/ESD performance, ultra-low power management, and comprehensive protective features, making it an optimal choice for critical automotive network applications.
