The TLIN1039DDFRQ1 is a Local Interconnect Network (LIN) transceiver designed by Texas Instruments (TI) specifically for automotive applications. The device complies with the LIN 2.x, and SAE J2602 standards, and supports the LIN protocol for scalable, reliable, and cost-effective in-vehicle networking. The TLIN1039DDFRQ1 is designed to interface between the LIN master/slave protocol controller and the physical bus in a LIN network. It features excellent electromagnetic compatibility (EMC) performance and robust electrostatic discharge (ESD) protection, ensuring reliable operation in the harsh automotive environment. The device supports a wide operating voltage range, accommodating the fluctuations in automotive power supplies, and includes features such as thermal shutdown and current limiting to protect against fault conditions. Its low-power sleep mode with wake-up capability enables significant power savings, a critical requirement for modern vehicles. Packaged in a compact DDF (DQFN) package, the TLIN1039DDFRQ1 is designed for minimal footprint and efficient communication in automotive body control modules, sensor interfaces, and actuator drives, among others.
