TLIN2029DRBRQ1

The TLIN2029-Q1 is a Local Interconnect Network (LIN) physical layer transceiver that integrates wake-up and protection functions and is compatible with the LIN 2.0, LIN 2.1, LIN 2.2, LIN 2.2 A, and ISO/DIS 17987–4.2 standards. LIN is a single-wire bidirectional bus commonly used in in-vehicle networks with data transfer rates up to 20 kbps. The TLIN2029-Q1 is designed to support 12V applications, featuring a wider operating voltage range and additional bus fault protection. The LIN receiver supports data transfer rates up to 100 kbps, enabling faster in-line programming. The TLIN2029-Q1 uses a current-limiting waveform shaping driver that reduces electromagnetic emissions (EME) to convert the data stream on the TXD input into a LIN bus signal. The receiver converts the data stream into a logic-level signal, which is sent to the microprocessor through the open-drain RXD pin. The sleep mode enables ultra-low current consumption and allows wake-up via the LIN bus or the EN pin. The integrated resistors, electrostatic discharge (ESD), and fault protection functions help designers save board space in their applications.
