The TLE7258D 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 up to 20 kbps. The TLE7258D 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 TLE7258D can be used in all automotive applications.
In Sleep mode the TLE7258D draws typically less than 10 μA of quiescent current while still being able to wake-up when detecting LIN bus traffic. The very low leakage current on the BUS pin makes the TLE7258D especially suitable for partially supplied networks.
Based on the Infineon BiCMOS technology the TLE7258D provides excellent ESD robustness together with a very high electromagnetic compatibility (EMC). The TLE7258D reaches a very low level of electromagnetic emission (EME) within a broad frequency range and independent from the battery voltage. The TLE7258D is AEC qualified and tailored to withstand the harsh conditions of the automotive environment.
