TLIN2022DRQ1

TLIN2022DRQ1 is a dual local Interconnect network (LIN) physical layer transceiver with integrated wake-up and protection features, complaint to 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 upto 20kbps. It is designed to support 24V applications with wider operating voltage and additional bus-fault protection. The LIN receiver supports data rates upto 100kbps for in-line programming. It 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. It is used in applications such as body electronics and lighting, hybrid electric vehicles and power train systems, infotainment, and cluster, appliances.
