Infineon TLE9251VSJXUMA1 CAN Bus Transceiver for Automotive Networking Applications

The evolution of automotive electronics has driven the demand for robust, reliable, and high-performance communication networks within vehicles. The Infineon TLE9251VSJXUMA1 stands out as a state-of-the-art CAN bus transceiver designed specifically to meet the stringent requirements of modern automotive networking applications. This integrated circuit serves as a critical interface between the controller area network (CAN) protocol controller and the physical bus wires, ensuring seamless and error-free data transmission across the vehicle.

A key feature of the TLE9251VSJXUMA1 is its compliance with the ISO 11898-2:2016 standard, which defines the high-speed medium access unit for CAN. This ensures full interoperability with other CAN devices in automotive systems, supporting data rates of up to 2 Mbit/s. The device is engineered for exceptional electromagnetic compatibility (EMC) and low electromagnetic emission (EME), which are crucial for minimizing interference with sensitive automotive electronics such as ADAS sensors, infotainment systems, and engine control units.

The transceiver also incorporates advanced protection mechanisms to enhance system reliability. It features high electrostatic discharge (ESD) protection up to 8 kV, safeguarding the device and the network from voltage spikes commonly encountered in automotive environments. Additionally, it offers over-temperature and short-circuit protection, ensuring continuous operation under fault conditions without damage. The low-power management capabilities, including a standby mode with very low current consumption, make it ideal for applications where energy efficiency is paramount, such as in always-on systems or battery-electric vehicles.

With its small PG-VDSO-14 package, the TLE9251VSJXUMA1 is optimized for space-constrained applications, providing a compact solution without compromising performance. Its AEC-Q100 qualification guarantees that it meets the rigorous quality and reliability standards required for automotive components, ensuring long-term durability across a wide temperature range.

ICGOODFIND: The Infineon TLE9251VSJXUMA1 is a highly integrated, robust, and efficient CAN transceiver that addresses the core needs of automotive networking. Its combination of high-speed performance, superior protection features, and low power consumption makes it an excellent choice for next-generation vehicle architectures.
