TLE7257LEXUMA1

TLE7257LEXUMA1 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. It 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 like 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.
