Texas Instruments TLIN1027-Q1/TLIN2027-Q1 LIN Transceiver

Texas Instruments TLIN1027-Q1/TLIN2027-Q1 LIN Transceiver is a local interconnect network (LIN) physical layer transceiver with integrated wake-up and protection features. It is also compatible with LIN 2.0, LIN 2.1, LIN 2.2, LIN 2.2A, and ISO/DIS 17987–4.2 standards. LIN is a single-wire bidirectional bus typically used for in-vehicle networks using data rates up to 20kbps. The TLIN1027-Q1 is designed to support 12V applications while the TLIN2027-Q1 supports 24V applications. Both come with wider operating voltage and additional bus-fault protection.

The LIN receiver supports data rates up to 100kbps for faster in-line programming. The Texas Instruments TLIN1027-Q1/TLIN2027-Q1 converts the data stream on the TXD input into a LIN bus signal using a current-limited wave-shaping driver, which reduces electromagnetic emissions (EME). The receiver converts the data stream to logic level signals that are sent to the microprocessor through the open-drain RXD pin. Ultra-low current consumption is possible using the sleep mode, which allows wake-up via LIN bus or EN pin.
