The TLIN1441-Q1 is a LocalInterconnect Network (LIN) physical layer transceiver with an integrated low dropout voltageregulator, wake up and protection features and is compliant to LIN 2.0, LIN 2.1, LIN 2.2, LIN2.2A and ISO/DIS17987–4.2 standards.The TLIN1441-Q1integrates a window or timeout based watchdog supervisor that is PIN or SPI configurable andcontrolled. The TLIN1441-Q1 watchdog is controlled by PIN strapping or SPI depending upon the stateof pin 9 at power up.

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 TLIN1441-Q1 converts theLIN protocol data stream on the TXD input into a LIN bus signal using a current-limitedwave-shaping driver which reduces electromagnetic emissions (EME). The receiver converts the datastream to logic level signals that are sent to the microprocessor through the open-drain RXDpin.

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 required an external pull-up resistor (1 kΩ) plus a series diodeper the LIN specification.
