The TLE7259-2GE 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 TLE7259-2GE 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 TLE7259-2GE can be used in all automotive applications. Different operation modes and the INH output allow the TLE7259-2GE to control external components, like voltage regulators. In Sleep-mode the TLE7259-2GE draws less than 8 μA 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 TLE7259-2GE especially suitable for partially supplied networks and supports the low quiescent current requirements of the LIN network. Based on the Infineon Smart Power Technology SPT®, the TLE7259-2GE provides excellent ESD Robustness together with a very high electromagnetic immunity (EMI). The TLE7259-2GE 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 TLE7259-2GE and the Infineon SPT® technology are AEC qualified and tailored to withstand the harsh condition of the Automotive Environment.
