The TLIN1124A-Q1 device is a quad Local Interconnect Network (LIN) physical layer transceiver with integrated commander and responder termination, inhibit, wake-up and protection features, complaint to LIN 2.0, LIN 2.1, LIN 2.2, LIN 2.2A, ISO/DIS 17987-4 and SAE J2602-1 standards.

LIN is a single wire bidirectional bus typically used for low speed in-vehicle networks using data rates up to 20kbps. The LIN receiver supports data rates up to 100kbps for in-line programming.

The TLIN1124A-Q1device supports 12V battery applications with wider operating voltage (5V to 28V) and extended LIN bus-fault (±40V) protection. The device converts the LIN protocol data stream on the TXDx input into a LINx bus signal using a current-limited wave-shaping driver which reduces electromagnetic emissions (EME). The receiver converts the data stream to logic level signals that are sent to the microprocessor through the push-pull RXD output pin. Ultra-low current consumption is possible using the sleep mode which allows wake up via LIN bus or SLP pin.

The integrated commander and responder diode and resistor, electrostatic discharge (ESD) protection, and fault protection allow designers to save board space in the system. The device prevents back-feed current through LIN to the supply if the ground shift or supply voltage is disconnected.
