Product Brief
TLE7258D
Basic LIN Transceiver without TxD Time-Out
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 20kbps. Additionally the TLE7258D has no TxD time-out feature and
therefore can communicate at very low baud-rates, supporting ISO 9141, K-Line and even
MOST ECL serial communication protocols.
Being compliant to all LIN standards and with a wide operational voltage supply range,
the TLE7258D can be used in all automotive applications.
In Sleep mode the TLE7258D 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 TLE7258D especially suitable for partially supplied networks.
The TLE7258D 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 TLE7258D is AEC qualified and tailored to withstand the harsh conditions of the
automotive environment.
