The TLIN2024A-Q1 device is a Quad Local Interconnect Network (LIN) physical layer transceiver, which integrates wake-up and protection features, compliant to LIN2.0, LIN2.1, LIN2.2, LIN2.2A 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 20 kbps. The TLIN2024A-Q1 is designed to support 12-V and 24-V applications with wider operating voltage and additional bus-fault protection. The device has two separate dual LIN transceiver blocks. The VSUP1/2 control separate dual transceiver blocks.

The TLIN2024A-Q1 receiver supports data rates up to 100 kbps for faster in-line programming. The device 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 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.
