Infineon TLE7250GV10: High-Speed CAN Transceiver for Automotive Networks

The evolution of automotive electronics towards greater connectivity, automation, and electrification demands robust and reliable communication networks. The Controller Area Network (CAN) remains the backbone for in-vehicle communication, and its effectiveness hinges on the performance of the transceiver ICs that interface between the protocol controller and the physical bus. The Infineon TLE7250GV10 stands out as a premier high-speed CAN transceiver engineered specifically to meet the stringent requirements of modern automotive applications.

This transceiver is designed for high-speed CAN networks operating at speeds up to 1 Mbit/s, making it ideal for critical powertrain, chassis, and body control modules where real-time data exchange is paramount. Its core functionality is to convert the digital data streams from a CAN controller into differential signals on the bus and vice versa, ensuring data integrity in the electrically noisy environment of a vehicle.

A key strength of the TLE7250GV10 is its exceptional electromagnetic compatibility (EMC) performance and high electrostatic discharge (ESD) robustness. It incorporates advanced features such as excellent passive behavior when unpowered, which is crucial for automotive networks where modules may be in different power states. The device also offers a very low-current standby mode with bus wake-up capability, enabling the design of energy-efficient systems that are essential for electric and hybrid vehicles.

Furthermore, the transceiver provides enhanced system security and diagnostic capabilities. It includes comprehensive protection features like overtemperature shutdown, undervoltage detection on both VCC and VIO supplies, and dominant time-out to prevent the bus from being locked by a faulty controller. These built-in safeguards contribute significantly to the overall functional safety of the vehicle system, aligning with standards such as ISO 11898-2 and ISO 11898-5.

Housed in a compact, green SG-DSO-8 package, the TLE7250GV10 is fully AEC-Q100 qualified, guaranteeing its reliability and performance across the harsh automotive temperature range and lifetime. Its compatibility with 3.3 V and 5 V microcontrollers adds to its design flexibility, making it a versatile choice for a wide array of electronic control units (ECUs).

ICGOOFind: The Infineon TLE7250GV10 is a high-performance, robust, and feature-rich high-speed CAN transceiver that serves as a critical enabler for next-generation automotive networking. Its combination of superior EMC/ESD performance, low-power operation, and integrated diagnostic functions makes it an optimal solution for building reliable and safe in-vehicle communication systems.
