BDTIC
Basic LIN Transceiver starting up in Sleep Mode
The TLE7257SJ 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 20kbps. The TLE7257SJ 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 voltage supply range, the TLE7257SJ can be used in
all automotive applications.
Key Features
The usage of different operation modes and the INH output allows the TLE7257SJ to
control external components like e.g. voltage regulators. In sleep mode the TLE7257SJ
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
TLE7257SJ especially suitable for partially supplied networks.
„„ Worldwide OEM approval
„„ Data rates up to 20kBaud
„„ Compliant to ISO 17987-4, LIN
Specification 2.2A and SAE J2602
„„ Very high ESD robustness of ±10kV
according IEC61000-4-2 and HBM
„„ Low electromagnetic emission
„„ High immunity against EMI
„„ Very low current consumption in
sleep mode (10µA)
„„ Digital I/O levels compatible for
The TLE7257SJ provides excellent ESD robustness together with a very high electromagnetic compatibility (EMC). It reaches a very low level of electromagnetic emission
(EME) within a broad frequency range and independent from the battery voltage. The
TLE7257SJ is AEC qualified and tailored to withstand the harsh conditions of the automotive environment.
