The TLIN1021-Q1 is a local interconnect network (LIN) physical layertransceiver, compliant to LIN 2.2A and ISO/DIS 17987-4.2 standards. LIN is a single-wirebidirectional bus typically used for in-vehicle networks using data rates up to 20 kbps. Thereceiver supports data rates up to 100 kbps for end-of-line programming. TheTLIN1021-Q1 controls the state of the LIN bus via the TXD pin and reports the stateof the bus on the open-drain RXD pin. The TLIN1021-Q1 is designed to support12 V applications across a wide operating voltage and protectagainst DC faults with integrated protection. Ultra-low current consumption is possible by puttingthe device in sleep mode and can be put in normal mode via messages on the LIN bus, the WAKE pin,or the EN pin. The TLIN1021-Q1 allows for system-level reductions in battery currentconsumption by selectively enabling, via the INH output pin, the various power supplies that may bepresent on a node. The TLIN1021-Q1 has a current-limited wave-shaping driver toreduce electromagnetic emissions (EME).

The integrated resistor, electrostatic discharge (ESD) protection, and fault protectionallow designers to save board in their applications. The TLIN1021-Q1 has beendesigned for operation in the harsh automotive environment. The device prevents back-feed currentthrough LIN to the supply input in case of a ground shift or supply voltage disconnection. Otherfeatures include undervoltage, overtemperature, and loss-of-ground protection. In the event of afault condition, the transmitter is immediately switched off and remains off until the faultcondition is removed.
