The TLE7269G is designed for in-vehicle networks using data transmission rates from 2.4 kBaud to 10.4 kBaud according to the SAE J2602 standard. The TLE7269G 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 TLE7269G can be used in all automotive applications.Different operation modes and the INH output allow the TLE7269G to control external components, like voltage regulators. In Sleep-mode the TLE7269G 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 TLE7269G 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 TLE7269G provides excellent ESD Robustness together with a very high electromagnetic immunity (EMI). The TLE7269G reaches a very low level of electromagnetic emission (EME) within a broad frequency range and independent form 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 TLE7269G and the Infineon SPT® technology are AEC qualified and tailored to withstand the harsh condition of the Automotive Environment.
