Infineon TLE6259-2G: A High-Speed CAN Transceiver for Automotive Network Applications
The evolution of modern vehicles into complex, software-defined systems hinges on the robust and reliable exchange of data between electronic control units (ECUs). At the heart of this communication lies the Controller Area Network (CAN), the established backbone for in-vehicle networking. The Infineon TLE6259-2G stands as a pivotal component in this ecosystem, representing a highly integrated and resilient high-speed CAN transceiver designed to meet the stringent demands of the automotive industry.
This transceiver serves as the critical interface between the protocol-handling CAN controller and the physical CAN bus lines. It is engineered to convert the digital data streams from the controller into differential signals for transmission over the bus and to translate received differential signals back into digital data for the microcontroller. A key attribute of the TLE6259-2G is its full compliance with the ISO 11898-2 and ISO 11898-5 standards, ensuring interoperability and performance integrity within international automotive networking frameworks.
The device is optimized for high-speed CAN networks operating at bit rates up to 1 Mbit/s. It is particularly suited for powertrain, chassis, and body control applications where real-time performance and data integrity are non-negotiable. Exceptional electromagnetic compatibility (EMC) and electrostatic discharge (ESD) protection are hallmarks of its design, safeguarding the network and the ECU from electrical disturbances prevalent in the harsh automotive environment. Features such as excellent radio frequency interference (RFI) suppression and very low electromagnetic emission (EME) contribute to a stable and noise-resistant network.
Furthermore, the TLE6259-2G incorporates advanced protection and diagnostic features that enhance system reliability. These include undervoltage detection, thermal shutdown, and bus fault protection against short circuits to ground or battery voltage. Its low-power management capabilities, including a standby mode with remote wake-up functionality via the bus, are essential for supporting modern energy-saving requirements in vehicles, helping to minimize quiescent current and extend battery life.
In application, the transceiver offers ease of design-in with its single-chip solution that requires very few external components. Its small PG-DSO-8 package makes it ideal for space-constrained ECU designs. From advanced driver-assistance systems (ADAS) to gateway modules and engine control units, the TLE6259-2G provides a dependable communication link that is vital for safety and functionality.
The Infineon TLE6259-2G is a robust, high-performance CAN transceiver that embodies the reliability required for next-generation automotive networks. Its comprehensive feature set, focusing on compliance, protection, and low-power operation, makes it an indispensable component for ensuring secure and efficient data communication across a vehicle's electronic systems.
