Overview

The TLIN1021ADRQ1 is a Local Interconnect Network (LIN) physical layer transceiver with integrated wake-up and protection features. It is AEC-Q100 qualified for automotive applications and supports data rates up to 20 kbps for transmission and 100 kbps for end-of-line programming.

Why Choose This Part

This transceiver offers high robustness with +/-45V fault tolerance on the LIN bus and 42V load dump protection, reducing the need for external protection components. Its ultra-low power sleep mode (9 uA) and integrated INH pin for system-level power management make it excellent for battery-sensitive applications.

Applications

Automotive Body Control Modules
Used to interface low-speed sensors and actuators like door locks, window lifts, and seat adjusters to the vehicle network.
Infotainment Systems
Provides a robust communication link for user interface panels and steering wheel controls.
Industrial Sensor Networks
Ideal for long-distance sensor communication in industrial environments where 24V supply rails are common.

Getting Started

To evaluate this part, designers can use the TLIN1021EVM evaluation module from Texas Instruments. Ensure that the VSUP pin is decoupled with a 100nF capacitor and the TXD dominant state time-out is accounted for in the software driver to prevent bus blocking.
