Infineon TLE6250PG: A Robust Single-Wire CAN Transceiver for Demanding Automotive Networks
The evolution of automotive electronics necessitates reliable and cost-effective communication networks. The Infineon TLE6250PG stands out as a highly integrated single-wire CAN (Controller Area Network) transceiver, specifically engineered to meet the stringent requirements of modern vehicle systems. This device serves as the critical physical interface between a protocol controller and the data bus, enabling robust serial data communication in low-to-medium speed applications such as body control modules, comfort systems, and sensor nodes.
A key advantage of the TLE6250PG is its implementation of a single-wire bus system. This design significantly reduces the physical wiring harness complexity, weight, and associated costs compared to a traditional two-wire CAN setup. Despite using a single line for data transmission, the transceiver incorporates sophisticated features to ensure signal integrity. It is designed to be fully compliant with the SAE J2411 standard, which defines the single-wire data transmission protocol for automotive applications. This ensures interoperability with other compliant devices in the network.
The transceiver is built for the harsh automotive environment. It offers excellent ESD (Electrostatic Discharge) protection, exceeding 8 kV, which is crucial for preventing damage during handling and operation. Furthermore, it demonstrates high resilience against electromagnetic interference (EMI) and provides robust overvoltage and reverse voltage protection on the bus pin. This makes the TLE6250PG exceptionally reliable in the face of electrical transients commonly found in vehicles.
Internally, the device features a wake-up capability via the bus, allowing it to manage power consumption effectively for applications requiring a low-power sleep mode. Its low-current standby mode is essential for minimizing quiescent current, a critical parameter for preserving battery life in today's feature-rich vehicles. The TLE6250PG also supports baud rates up to 50 kbit/s, which is ideal for its target applications where high speed is not the primary concern, but reliability and cost are.
ICGOOODFIND: The Infineon TLE6250PG is a highly robust and cost-optimized single-wire CAN transceiver that simplifies in-vehicle networking. Its compliance with automotive standards, superior protective features, and low-power capabilities make it an ideal solution for enhancing reliability and reducing system cost in a wide array of body and comfort electronics.
