Infineon Technologies AG Transceivers - Automotive Transceivers - LIN Transceivers - TLE7259-3LE TLE7259-3LE

The TLE7259-3LE 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 kbps to 20 kbps. The TLE7259-3 operate as a bus driver between the protocol controller and the physical bus of the LIN network. Compliant to all LIN standards and with a wide operational supply range the TLE7259-3 can be used in all automotive applications.

The usage of different operation modes and the INH output allow the TLE7259-3 to control external components, like e.g. voltage regulators. In Sleep-mode the TLE7259-3 draws typically less than 8 μA of quiescent current while still being able to wake up when detecting LIN bus traffic and a local wake up signalst. The very low leakage current on the BUS pin makes the TLE7259-3 especially suitable for partially supplied networks.

Based on the Infineon Smart Power Technology SPT®, the TLE7259-3 provides excellent ESD Robustness and a very high electromagnetic compliance (EMC). The TLE7259-3 reaches very low levels of electromagnetic emission within a broad frequency range, independent from the battery voltage. The TLE7259-3 and the Infineon SPT® technology are AEC qualified and tailored to withstand the harsh condition of the automotive environment.
