Texas Instruments TLIN1022-Q1/TLIN2022-Q1 Dual LIN Transceivers
Texas Instruments TLIN1022-Q1/TLIN2022-Q1 Dual Local Interconnect Network (LIN) Transceivers are a physical layer transceiver with integrated wake-up and protection features. Each device complies with LIN 2.0, LIN 2.1, LIN 2.2, LIN 2.2A, and ISO/DIS 17987–4.2 standards. A LIN is a single-wire bidirectional bus typically used for low-speed in-vehicle networks using data rates up to 20kbps. The TLIN1022-Q1/TLIN2022-Q1 supports 12V (TLIN1022-Q1) or 24V (TLIN2022-Q1) 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 TLIN1022-Q1/TLIN2022-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.
