The TLIN1021-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 TLIN1021-Q1 transmitter supports data rates up to 20 kbps and the receiver supports data rates up to 100 kbps for faster 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 its open-drain RXD output pin. The device has a current-limited wave-shaping driver to reduce electromagnetic emissions (EME).

The TLIN1021-Q1 is designed to support 12-V applications with a wide input voltage operating range and also supports low-power sleep mode. The device supports wake-up from low-power mode via wake over LIN, the WAKE pin, or the EN pin. The device allows for system-level reductions in battery current consumption by selectively enabling the various power supplies that may be present on a node through the TLIN1021-Q1 INH output pin.

The TLIN1021-Q1 integrates a resistor for LIN responder applications, ESD protection, and fault protection which allow for a reduced amount of external components in the applications. The device prevents back-feed current through LIN to the supply input in case of a ground shift or supply voltage disconnection.
