TLIN2027DRQ1

Drivers, Receivers, Transceivers Overview

The TLIN2027DRQ1 is an automotive-grade LIN transceiver supporting 4-V to 48-V supply voltages and ±60-V bus fault protection. It operates within a temperature range of -40°C to 125°C and complies with AEC-Q100 Grade 1 standards. The device supports data rates up to 20 kbps for standard communication and up to 100 kbps for in-line programming. Supply current varies by mode: typical sleep current is 9 µA at 4–27 V and 30 µA at 27–48 V, while normal mode current reaches 2.1 mA under dominant load conditions. ESD protection ratings include ±8 kV HBM for the LIN pin and ±4 kV HBM for logic pins.

Drivers, Receivers, Transceivers Feature Summary

• Integrated wake-up functionality allowing system activation via LIN bus signals or local EN pin input.
• Enhanced electromagnetic compatibility through current-limited wave-shaping drivers that reduce emissions.
• Robust fault protection including ±60-V bus fault tolerance, thermal shutdown, and loss-of-ground/battery failsafe mechanisms.

Drivers, Receivers, Transceivers Applications

• Body electronics and lighting systems
• Infotainment and instrument clusters
• Hybrid electric vehicles and powertrain systems
• Passive safety modules
• Industrial appliances

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package variant (SOIC-8 or VSON-8) required for the design, as the base part number covers both. Confirm AEC-Q100 qualification status matches project requirements. Ensure supply voltage ranges align with the 4-V to 48-V operational limits. Check for any recent documentation revisions affecting electrical characteristics or pin functions before finalizing procurement.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing for 24-V automotive networks requiring high fault tolerance. Choose the SOIC package for standard automated optical inspection needs or VSON for compact layouts. Consider the absence of dominant state timeout if long dominant periods are expected on the bus. Evaluate thermal performance based on the junction-to-ambient resistance of the chosen package type.

Drivers, Receivers, Transceivers Part Context

This device belongs to Texas Instruments' TLIN202x-Q1 family of LIN transceivers. It shares functional similarities with other members like the TLIN2022 but distinguishes itself by lacking dominant state timeout features and offering extended ±60-V fault protection. It serves as a physical layer interface between microcontrollers and the LIN bus in demanding automotive environments.

Drivers, Receivers, Transceivers Replacement Considerations

TLIN2022DRQ1 offers similar functionality but includes dominant state timeout protection. TLIN1029DRQ1 provides integrated LDO regulation and different fault protection levels. Verify pinout compatibility and specific timing requirements when substituting these alternatives.
