Texas Instruments TLIN1029-Q1/TLIN1029A-Q1 LIN Transceiver
Texas Instruments TLIN1029-Q1/TLIN1029A-Q1 Local Interconnect Network (LIN) Transceiver is a physical layer transceiver with integrated wake-up and protection features. The device complies 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 low-speed in-vehicle networks using data rates up to 20kbps. The TLIN1029-Q1/TLIN1029A-Q1 is designed to support 12V applications with wider operating voltage and additional bus-fault protection.
The LIN receiver supports data rates up to 100kbps for in-line programming. The Texas Instruments TLIN1029-Q1/TLIN1029A-Q1 converts the LIN protocol 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 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 pin. The integrated resistor, ESD, and fault protection allow designers to save board space in their applications.
