The TLE7268 is designed for in-vehicle networks using data transmission rates up to Data Sheet 1 Rev. 1.0 www.infineon.com/automotive-transceiver 2017-09-14 TLE7268 Dual LIN 2.2 / SAE J2602 Transceiver Overview 20kbps. The TLE7268 includes two independent transceivers that operate as bus drivers between the protocol controller and physical LIN networks. The TLE7268 supports different modes of operation of the two transceivers for minimizing ECU current consumption in low power modes. When both transceivers are in Sleep mode, the TLE7268 typically draws a quiescent current of less than 10 A, while they still can wake up on detecting LIN bus traffic on either bus channel. A common INH output can be used for controlling external circuitry, for example voltage regulators. Based on the Infineon BiCMOS technology the TLE7268 provides excellent ESD robustness together with very high electromagnetic compliance (EMC). The TLE7268 reaches a very low level of electromagnetic emission (EME) within a broad frequency range and independent from the battery voltage. The TLE7268 is AEC qualified and tailored to withstand the harsh conditions of automotive environment.
