The TLIN1021-Q1 is a local interconnect network (LIN) physical layer transceiver, compliant to LIN 2.2A and ISO/DIS 17987-4.2 standards. LIN is a single-wire bidirectional bus typically used for in-vehicle networks using data rates up to 20 kbps. The receiver supports data rates up to 100 kbps for end-of-line programming. The TLIN1021-Q1 controls the state of the LIN bus via the TXD pin and reports the state of the bus on the open-drain RXD pin. The TLIN1021-Q1 is designed to support 12 V applications across a wide operating voltage and protect against DC faults with integrated protection. Ultra-low current consumption is possible by putting the 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 current consumption by selectively enabling, via the INH output pin, the various power supplies that may be present on a node. The TLIN1021-Q1 has a current-limited wave-shaping driver to reduce electromagnetic emissions (EME).
