TLIN4029ADRBRQ1-Texas Instruments-Price, Stock & Datasheet

The TLIN4029A-Q1 is a local interconnect network (LIN) physical layer transceiver with integrated wake-up and protection features, compliant with LIN 2.0, LIN 2.1, LIN 2.2, LIN 2.2 A and ISO 17987–4 standards. LIN is a single-wire bidirectional bus typically used for in-vehicle networks using data rates up to 20kbps. The TLIN4029A-Q1 is designed to support 12V LIN and 24V LIN applications with wider operating voltage and extended ±70V bus-fault protection.

The LIN receiver supports data rates up to 100kbps for faster in-line programming. The TLIN4029A-Q1 converts the data stream on the TXD input into a LIN bus signal using a current-limited wave-shaping driver which reduces electromagnetic emissions (EME). The receiver converts the data stream to logic level signals that are sent to the microprocessor through the open-drain RXD pin. Ultra-low current consumption is possible using the sleep mode which allows wake-up via LIN bus or EN pin.

The TLIN4029A-Q1 integrates a resistor for LIN responder node 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. The TLIN4029A-Q1 also includes undervoltage detection, temperature shutdown protection, and loss-of-ground protection.
