Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

In the field of automotive electronics, reliable communication technology is critical to ensuring vehicle safety and efficient operation. As a leading supplier of electronic components, Mingjiada Electronics is proud to introduce Infineon's TLE7259-3GE automotive LIN transceiver to the market. This high-performance transceiver is specifically designed for automotive local interconnect networks (LIN) and integrates multiple advanced features to meet the stringent data communication requirements of modern vehicles.

Description  

The TLE7259-3GE is a LIN transceiver with integrated wake-up and protection functions. It is specifically designed for in-vehicle networks and supports data transfer rates ranging from 2.4 kbps to 20 kbps. The TLE7259-3GE operates as a bus driver between the protocol controller and the physical bus in the LIN network. The device complies with all LIN standards and has a wide supply voltage range, making it suitable for use in various automotive electronic systems.

By supporting different operating modes and INH output, the TLE7259-3GE can control external components such as voltage regulators. In sleep mode, the TLE7259-3GE typically has a static current of less than 8 μA while still being able to detect LIN bus traffic and wake up when a local wake-up signal is detected. The extremely low leakage current on the bus pins makes the TLE7259-3GE particularly suitable for partially powered networks.

Based on Infineon's Smart Power Technology (SPT®), the TLE7259-3GE offers excellent electrostatic discharge (ESD) immunity and very high electromagnetic compatibility (EMC). The TLE7259-3GE achieves extremely low electromagnetic radiation levels across a wide frequency range, independent of battery voltage. The TLE7259-3GE and Infineon's SPT® technology are AEC-certified and optimised for the harsh conditions of automotive environments.
