Infineon TLE72593GEXUMA3 LIN Transceiver for Automotive Networking Applications

The evolution of modern vehicles into complex electronic systems has driven the need for reliable, cost-effective, and robust communication networks. While high-speed protocols like CAN and FlexRay handle critical data, there is a substantial demand for a simpler, more economical solution for managing communication with peripheral components like sensors, actuators, and switches. This is where the Local Interconnect Network (LIN) bus excels, and the Infineon TLE72593GEXUMA3 stands out as a premier transceiver designed specifically for these demanding automotive applications.

As a physical layer interface, the TLE72593GEXUMA3 facilitates communication between a LIN master/master node (typically a microcontroller) and various LIN slave nodes. Its primary function is to translate the digital signals from the microcontroller into the bus voltage levels required by the LIN protocol and vice-versa. This device is engineered to meet the stringent requirements of the latest LIN 2.2/SAE J2602 and LIN 1.3 standards, ensuring full compatibility and interoperability within a vehicle's network architecture.

A key strength of the TLE72593GEXUMA3 lies in its robustness and diagnostic capabilities. Operating within a wide supply voltage range from 5.5 V to 27 V, it is inherently resilient against the voltage fluctuations and transients common in the automotive electrical environment. It offers excellent electromagnetic compatibility (EMC) and very low electromagnetic emission (EME), which is crucial for preventing interference with sensitive electronic equipment. Furthermore, it incorporates comprehensive protection features, including over-temperature and over-voltage shutdown, as well as protection against loss of battery and ground.

The device also features a very low current consumption in sleep mode, typically as low as 6 µA. This ultra-low power characteristic is vital for modern vehicles, helping to minimize the quiescent current drain on the battery, which is a critical parameter for meeting the power management goals of today's automobiles, especially those with start-stop systems.

Housed in a compact, surface-mountable SG-8 package, the TLE72593GEXUMA3 is optimized for space-constrained applications. Its AEC-Q100 qualification guarantees its performance and reliability under the harsh operating conditions of an automotive environment, including extreme temperatures and humidity.

ICGOOFind: The Infineon TLE72593GEXUMA3 is a highly integrated and robust LIN transceiver that provides a reliable communication backbone for sub-networks in automotive applications. Its combination of standards compliance, exceptional robustness, comprehensive diagnostic features, and ultra-low power consumption makes it an ideal choice for designers building next-generation vehicle systems that demand both performance and reliability.
