Texas Instruments TLIN24415DMTTQ1

The TLIN2441-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 TLIN2441-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 TLIN2441-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 TLIN2441-Q1 reduces system complexity by providing a 3.3 V or 5 V rail with up to 70 mA of current to power microprocessors, sensors or other devices. The TLIN2441-Q1 has an optimized current-limited wave-shaping driver which reduces electromagnetic emissions (EME).
