The TLIN1028-Q1 is a local interconnect network (LIN) physical layertransceiver, compliant to LIN 2.2A ISO/DIS 17987–4.2 standards, with anintegrated low dropout (LDO) voltage regulator.

LIN is a single-wire bidirectional bus typically used for low speed in-vehicle networksusing data rates up to 20 kbps. The LIN receiver supports data rates up to 100 kbps for end-of-lineprogramming. The TLIN1028-Q1 converts the LIN protocol data stream on the TXDinput into a LIN bus signal. The receiver converts the data stream to logic level signals that aresent to the microprocessor through the open-drain RXD pin. The TLIN1028-Q1reduces system complexity by providing a 3.3 V or 5 V rail with up to 70 mA(D) and 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 reduceselectromagnetic emissions (EME).

Ultra-low current consumption is possible using the sleep mode which allows wake up viaLIN bus or pin. The LIN bus has two states: dominant state (voltage near ground) and recessivestate (voltage near battery). In the recessive state, the LIN bus is pulled high by the internalpull-up resistor (45 kΩ) and a series diode. No external pull-up components are required for slaveapplications. Master applications require an external pull-up resistor (1 kΩ) plus a series diodeper the LIN specification.
