Infineon TLE9250XSJ: High-Speed CAN Transceiver for Automotive Networks

The evolution of modern vehicles into complex, software-defined systems has intensified the demand for robust and reliable communication networks. At the heart of these in-vehicle networks (IVNs), the Controller Area Network (CAN) remains a cornerstone technology. The Infineon TLE9250XSJ stands out as a state-of-the-art high-speed CAN transceiver, engineered to meet the stringent requirements of next-generation automotive applications.

This transceiver serves as the critical interface between a microcontroller's CAN protocol controller and the physical CAN bus lines. It is designed for high-speed CAN networks operating at speeds up to 8 Mbit/s in CAN FD (Flexible Data-rate) mode, significantly enhancing data throughput compared to classical CAN. This capability is essential for bandwidth-intensive applications like advanced driver-assistance systems (ADAS), electrified powertrains, and high-end body control modules.

A key strength of the TLE9250XSJ is its robust ESD protection and electromagnetic compatibility (EMC). It incorporates advanced features to protect sensitive electronic control units (ECUs) from electrostatic discharge (ESD) and transients common in the harsh automotive environment. Its excellent EMC performance ensures minimal electromagnetic emissions, preventing interference with other systems, and provides high immunity against external noise.

Furthermore, the device offers advanced power management functionality, including multiple low-power modes. This feature is crucial for modern vehicles, supporting applications that require minimal quiescent current to extend battery life, such as in wake-up/sleep systems and always-on functionalities. The TLE9250XSJ also provides comprehensive diagnostic capabilities, allowing for the monitoring of bus states, battery voltage, and internal temperature, which aids in system-level debugging and functional safety compliance.

Fully compliant with the ISO 11898-2:2016 and SAE J2284 standards, the TLE9250XSJ is qualified for automotive AEC-Q100 Grade 1, ensuring reliable operation in a temperature range from -40°C to 125°C. Its compact VSON-8 package makes it suitable for space-constrained applications.

ICGOODFIND: The Infineon TLE9250XSJ is a premier high-speed CAN FD transceiver that delivers a powerful combination of high data rates, exceptional robustness, and intelligent power management. It is an optimal solution for designers building reliable and efficient communication networks for the automotive industry's future.
