Texas Instruments TLIN2022A-Q1 Dual LIN Transceiver
Texas Instruments TLIN2022A-Q1 Dual Local Interconnect Network (LIN) Transceiver has integrated wake-up and protection features, compliant with LIN 2.0, LIN 2.1, LIN 2.2, LIN 2.2A and ISO/DIS 17987–4 standards. LIN is a single-wire bidirectional bus typically used for low-speed in-vehicle networks using data rates up to 20kbps. The TLIN2022A-Q1 supports 12V and 24V applications 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 TLIN2022A-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 EN pin.
