Infineon TLE6250GV33XUMA1 High-Speed CAN Transceiver for Automotive Applications

The Infineon TLE6250GV33XUMA1 is a monolithic high-speed Controller Area Network (CAN) transceiver, specifically engineered to meet the rigorous demands of automotive electronic systems. As a key interface between a CAN protocol controller and the physical differential bus lines, this device plays a fundamental role in enabling robust and reliable communication within vehicles, which is critical for applications ranging from powertrain and chassis control to body electronics and infotainment systems.

A primary strength of the TLE6250GV33XUMA1 is its exceptional robustness and electromagnetic compatibility (EMC). It is designed to withstand the harsh electrical environment of an automobile, offering excellent ESD protection up to ±8 kV (according to IEC 61000-4-2) on the bus pins. This high level of protection safeguards the transceiver and the connected electronic control units (ECUs) from electrostatic discharge events that can occur during manufacturing or maintenance. Furthermore, its high immunity to electromagnetic interference (EMI) ensures stable data transmission without errors, even when operating in close proximity to high-power loads like motors or solenoids.

The device is fully compliant with the ISO 11898-2 and ISO 11898-5 standards, guaranteeing interoperability within the established CAN automotive network architecture. It supports a high data rate of up to 1 Mbit/s, which is essential for real-time control applications where latency must be minimized. A critical feature for automotive safety and power management is its low-current standby mode with bus wake-up capability. This allows the ECU to enter a low-power state when the vehicle is idle but can be quickly awakened by a message on the CAN bus, contributing to overall energy efficiency and meeting strict automotive quiescent current requirements.

The TLE6250GV33XUMA1 also incorporates advanced failure detection and management features. It provides comprehensive diagnostic capabilities, including thermal shutdown, undervoltage detection on both VCC and VIO supplies, and permanent dominant detection. These features allow the system to identify faults and take appropriate action, enhancing the overall reliability and functional safety of the network. Its green SG-HVQFN-14 package is optimized for automated assembly and offers a compact footprint, which is vital for space-constrained automotive module designs.

ICGOODFIND: The Infineon TLE6250GV33XUMA1 stands out as a highly robust and reliable solution for in-vehicle networking. Its superior EMC performance, comprehensive diagnostic suite, and low-power management features make it an ideal choice for designers building next-generation automotive ECUs that demand unwavering communication integrity and efficiency.
