Overview
The TLE7259-3GE, produced by Infineon Technologies, is a high-end transceiver designed for the Local Interconnect Network (LIN) in automotive applications. It integrates wake-up and protection features, making it suitable for in-vehicle networks with data transmission rates ranging from 2.4 kBaud to 20 kBaud. This transceiver functions as a bus driver between the protocol controller and the physical bus of the LIN network, ensuring compliance with all LIN standards. The TLE7259-3GE is built using Infineon’s Smart Power Technology (SPT®), which provides excellent ESD robustness, high electromagnetic immunity (EMI), and low electromagnetic emission (EME) across a broad frequency range.
