TLE7257SJXUMA1

TLE7257SJXUMA1 is a LIN transceiver. It is a transceiver for the local interconnect network (LIN) with integrated wake-up and protection features. The TLE7257 operates 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 TLE7257 can be used in all automotive applications. The usage of different operation modes and the INH output allows the TLE7257 to control external components e.g. voltage regulators. In sleep mode, the TLE7257 draws typically less than 10μA 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 TLE7257 especially suitable for partially supplied networks. Based on the Infineon BiCMOS technology the TLE7257 provides excellent ESD robustness together with a very high electromagnetic compatibility (EMC).
