Automotive Local Interconnect Network (LIN) Transceiver with Integrated Voltage Regulator



The TLIN1028S-Q1 is a local interconnect network (LIN) physical layer transceiver, compliant to LIN 2.2A ISO/DIS 17987–4.2 standards, with an integrated low dropout (LDO) voltage regulator.

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 TLIN1028S-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 TLIN1028S-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 TLIN1028S-Q1 has an optimized current-limited wave-shaping driver which reduces electromagnetic emissions (EME).

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