The TLIN1441-Q1 is a local interconnect network (LIN) physical layer transceiver, compliant to LIN 2.2A and ISO/DIS 17987–4 standards, with an integrated low dropout (LDO) voltage regulator and watchdog. The TLIN1441-Q1 watchdog can operate in window or timeout mode and can be controlled by pins or SPI. The Pin or SPI control is established at power up by the state of pin 9 (that is, High, Z-State, Low).

LIN is a single-wire bidirectional bus typically used for low speed in-vehicle networks using data rates up to 20 kbps. The LIN receiver supports data rates up to 100 kbps for end-of-line programming. The TLIN1441-Q1 converts the LIN protocol data stream on the TXD input into a LIN bus signal. The receiver converts the data stream to logic-level signals that are sent to the microprocessor through the open-drain RXD pin. The TLIN1441-Q1 reduces system complexity by providing a 3.3 V or 5 V rail with up to 125 mA of current to power microprocessors, sensors or other devices. The TLIN1441-Q1 has an optimized current-limited wave-shaping driver which reduces electromagnetic emissions (EME).
