TLIN2029DQ1

Drivers, Receivers, Transceivers Overview

The TLIN2029DQ1 is a single-channel Local Interconnect Network (LIN) transceiver manufactured by Texas Instruments, designed for automotive applications. It operates within a supply voltage range of 4 V to 36 V and supports data rates up to 20 kbps in compliance with LIN 2.0 through 2.2A standards. The device features an operating temperature range from -40°C to +125°C and is housed in an SOIC-8 package. Key electrical specifications include a maximum quiescent current of 1 mA and a propagation delay of 6 µs. It integrates fault protection mechanisms and dominant state timeout functionality to ensure robust communication on the LIN bus.

• Low-speed in-vehicle communication interfaces

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'DQ1' against the manufacturer's official documentation to confirm package type, temperature grade, and qualification status. Ensure compatibility with AEC-Q100 requirements if automotive reliability is mandated. Cross-reference the datasheet revision date to validate parameter accuracy before integration into design schematics.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a single-channel LIN transceiver with integrated fault protection and dominant state timeout is required. It is suitable for designs needing operation up to 36 V supply voltage and support for LIN protocols up to version 2.2A. Consider the SOIC-8 package constraints and thermal performance within the -40°C to +125°C operating range during PCB layout planning.
