SN65HVDA1040BQDRQ1 TI automotive LIN transceiver
The SN65HVDA1040BQDRQ1 is an Automotive Grade LIN (Local Interconnect Network) physical layer transceiver from Texas Instruments, qualified to AEC-Q100standards and designed to interface a LIN protocol controller with the physical bus line in 12-V automotive applications. This device supports LIN 2.0, LIN 2.1, LIN 2.2A, ISO 17987-4, and SAE J2602standards, operating from a nominal 12-V battery supply with a wide VSUP range of 5 V to 27 V and withstanding transients up to 40 V.
Key Features and Specifications
The SN65HVDA1040BQDRQ1 provides a single-wire LIN transceiver with a LIN output pin capable of sourcing up to 20 mA in dominant state and sinking up to 10 mA in recessive state, with ESD protection exceeding ±12 kV HBM on the LIN bus pin and ±8 kV IEC 61000-4-2 contact discharge. The device operates from a VIO pin (1.71 V to 5.5 V) that sets the logic threshold on TXD and RXD, enabling direct interfacing to 1.8-V, 2.5-V, 3.3-V, or 5-V microcontrollers without external level shifters. Dominant time-out is typically 6 ms to 15 ms, ensuring the transceiver automatically returns to recessive if the MCU fails to release TXD low, guarding against accidental bus blockage. Wake-up capability is supported both from the LIN bus (remote wake-up via dominant pulse) and locally via the WAKE pin, with the device exiting sleep mode and asserting the RXD pin low to notify the host controller. Thermal shutdown and undervoltage lockout (UVLO) protect the IC under fault conditions, and the device is characterized for the full automotive temperature range of –40 °C to +125 °C ambient. Propagation delay from TXD to LIN bus is typically 2 µs, with symmetry between dominant and recessive edges to maintain LIN timing margins.
Alternative LIN bus transceivers
1. SN65HVDA1040AQDRQ1: Earlier A-version of the same automotive LIN 2.0/2.1 transceiver in 8-SOIC with slightly different dominant time-out range and wake-up thresholds, pin-compatible and functionally interchangeable in most legacy designs.
2. TJA1020T/CM: NXP Semiconductors LIN 2.0/2.1/SAE J2602transceiver in SO-8 with similar 5–27 V VSUP range and sleep/wake features, often used as a second-source in European automotive platforms.
3. ATA6626C-GAQW: Microchip (Atmel) LIN system basis chip combining LIN transceiver + 3.3 V/5 V LDO regulator in SO-8.
