It features dominant state timeout (DTO) protection preventing bus lockup from stuck-dominant conditions. The wide 4V to 36V supply with \u00b145V bus fault protection provides robust operation. Ultra-low sleep current with both local (EN pin) and remote (LIN bus) wake-up minimizes battery drain.","working_principle":"The TLIN1029 converts between MCU UART signals and LIN bus levels. The transmitter drives the LIN bus through an internal MOSFET. The receiver decodes bus voltages using threshold comparators. In sleep mode, a wake-up detector monitors the bus. The DTO feature monitors TXD, forcing the driver inactive if TXD is held dominant beyond timeout, preventing bus lockup. An integrated 45k\u03a9 pull-up resistor with series diode supports slave node configurations.","pin_description":"
