TLIN2029-Q1数据手册TI中文资料规格书

描述 Description

TheTLIN2029-Q1is a Local Interconnect Network (LIN) physical layer transceiver with integrated wake-up andprotection features, complaint to LIN 2.0, LIN 2.1, LIN 2.2, LIN 2.2A and ISO/DIS 17987–4.2standards. LIN is a single wire bidirectional bus typically used for low speed in-vehicle networksusing data rates up to 20 kbps. The TLIN2029-Q1 is designed to support 24 V applications with wider operatingvoltage and additional bus-fault protection. The LIN receiver supports data rates up to 100 kbpsfor in-line programming. TheTLIN2029-Q1 converts the LIN protocol data stream on the TXD input into aLIN 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 themicroprocessor through the open-drain RXD pin. Ultra-low current consumption is possible using thesleep mode which allows wake-up via LIN bus or pin. The integrated resistor, ESD and faultprotection allows designers to save board space in their applications.
