Infineon TLE9255WSK: High-Speed CAN Transceiver for Automotive Networking
The evolution of automotive electronics demands robust, efficient, and high-performance communication systems. At the heart of many modern vehicle networks lies the Controller Area Network (CAN), a standard that enables microcontrollers and devices to communicate without a host computer. Infineon’s TLE9255WSK stands out as a state-of-the-art high-speed CAN transceiver, designed to meet the stringent requirements of next-generation automotive applications.
Engineered for reliability and performance, the TLE9255WSK serves as a physical interface between the CAN protocol controller and the physical bus lines. It supports high-speed data transmission up to 5 Mbit/s, making it suitable for time-critical applications such as powertrain systems, advanced driver-assistance systems (ADAS), and body control modules. Its ability to operate in harsh automotive environments is underscored by exceptional ESD protection and electromagnetic compatibility (EMC), ensuring signal integrity and system durability.
A key feature of the TLE9255WSK is its low-power management capability, including a dedicated sleep mode with very low current consumption. This is critical for electric and hybrid vehicles, where energy efficiency directly impacts range and performance. The device also offers advanced diagnostic functions, such as overtemperature detection, undervoltage monitoring, and bus fault reporting, which enhance system safety and simplify debugging.
Compliant with ISO 11898-2 and ISO 11898-5 standards, the TLE9255WSK is optimized for 12V and 24V automotive systems. Its compact VSOF-8 package allows for space-efficient PCB design, addressing the growing need for miniaturization in automotive electronics.
The Infineon TLE9255WSK is a versatile and resilient high-speed CAN transceiver that combines high data rates, robust protection features, and energy efficiency. It is an ideal solution for modern automotive networking, supporting the industry’s shift towards more connected and automated vehicles.
