The TLIN821-Q1 is a local interconnect network (LIN) physical layer transceiver. LIN is a low-speed universal asynchronous receiver transmitter (UART) communication protocol, that supports automotive in-vehicle networking.

The TLIN821-Q1 transmitter supports data rates up to 20kbps. The transceiver controls the state of the LIN bus through the TXD pin and reports the state of the bus on its open-drain RXD output pin. The device has a current-limited wave-shaping driver to reduce electromagnetic emissions (EME).

The TLIN821-Q1 is designed to support 12V applications with a wide input voltage operating range. The device supports low-power sleep mode, as well as wake-up from low-power mode through wake over LIN, the WAKE pin, or the EN pin. The device allows system-level reductions in battery current consumption, by selectively enabling the various power supplies that can be present on a node through the device INH output pin.

The device integrates a resistor for LIN responder node applications, ESD protection, and fault protection which allow a reduced amount of external components in the applications. The device prevents back-feed current through LIN to the supply input due to a ground shift or supply voltage disconnection.
