The TLIN1028-Q1 is a local interconnect network (LIN) physical layer transceiver, compliant to LIN 2.2A ISO/DIS 17987–4 standards, with an integrated low dropout (LDO) voltage regulator.

This LIN system basis chip (SBC) reduces system complexity by providing a 3.3 V or 5 V rail with up to 70 mA (D) or 125 mA (DRB and DDA) of current to power microprocessors, sensors or other devices. The TLIN1028-Q1 has an optimized current-limited wave-shaping driver which reduces electromagnetic emissions (EME). The TLIN1028-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.
