TITLIN1021ADRBRQ1

Overview

The TLIN1021ADRBRQ1 is a Local Interconnect Network (LIN) physical layer transceiver with integrated wake-up and protection features designed for automotive applications. It supports data rates up to 100kbps in fast mode and is compliant with LIN 2.0 through LIN 2.2A and ISO 17987-4 standards. The device is functional safety-capable and includes an integrated 45-kohm pull-up resistor to minimize external component count.

Why Choose This Part

This transceiver offers robust protection with +/-45V fault tolerance on the LIN bus and 42V load dump support, ensuring survival during battery transients. Its ultra-low sleep current of 22uA helps maintain strict vehicle ignition-off current budgets while supporting remote wake-up via the LIN bus or local WAKE pin. The inclusion of an INH pin allows for system-level power management by controlling external voltage regulators.

Applications

Getting Started

To evaluate this part, use a TI LIN transceiver evaluation module such as the TLIN1021EVM. Ensure your microcontroller UART is configured for the correct LIN frame format, including the break field and checksum, and provide a stable VSUP between 4.5V and 36V. Pay close attention to the DRB package thermal pad, which should be soldered to the PCB ground plane for optimal heat dissipation.
