TLE7259 Transceiver

For the Local Interconnect Network (LIN) with Integrated Wake-up and Protection Features

The TLE7259G is a transceiver for the Local Interconnect Network (LIN) with integrated wake-up and protection features. It is designed for in-vehicle networks using data transmission rates from 2.4 kBaud to 20 kBaud. The TLE7259G functions as a bus driver between the protocol controller and the physical bus inside the LIN network. Compliant to all LIN standards and with a wide operational supply range the TLE7259G can be used in all automotive applications. Different operation modes and the INH output allow the TLE7259G to control external components, like voltage regulators. In Sleep-mode it draws less than 8µA of quiescent current while still being able to wake up off of LIN bus traffic and a local wake-up input. The very low leakage current on the BUS pin makes the TLE7259G especially suitable for "Mixed Power Supply" applications and supports the low quiescent current requirements of the LIN network.

Advantage   • LIN Transceiver with Module Level ESD Performance; Approved at Major Car Manufacturers Applications   • Automotive Network Communications for subsystems; e.g. HVAC, Door Nodes, Smart Seats, Body Controllers, etc. Key Benefits to Customer   • Low quiescent current   • Outstanding ESD behavior –  In most cases no additional external ESD component is necessary, saving money, space & components   • Excellent EM Emission and Susceptibility behavior

Based on the Infineon Smart Power Technology SPT®, the TLE7259G provides excellent ESD Robustness together with a very high electromagnetic immunity (EMI). It also reaches a very low level of electromagnetic emission (EME) within a broad frequency range and independent from the battery voltage. The Infineon Smart Power Technology SPT® allows bipolar and CMOS control circuitry in accordance with DMOS power devices existing on the same monolithic circuit. The TLE7259G and the Infineon SPT® technology are AEC qualified and tailored to withstand the harsh condition of the Automotive Environment.
