Overview

The TLIN1039DDFRQ1 is an AEC-Q100 Grade 1 qualified Local Interconnect Network (LIN) physical layer transceiver with integrated surge protection. It is designed to support data rates up to 100kbps for fast programming while remaining compliant with LIN 2.0, 2.1, 2.2, 2.2A, and ISO/DIS 17987-4 standards. The device operates from a wide 4.5V to 36V supply range and features low-power sleep and standby modes for energy-efficient automotive networking.

Why Choose This Part

This transceiver offers functional safety capability and integrated 45 kOhm pull-up resistors to reduce external component count. It provides robust protection features including TXD dominant time-out, thermal shutdown, and undervoltage lockout to ensure reliable operation in harsh automotive environments. The device is also designed for low electromagnetic emissions and high immunity to interference.

Applications

Body Electronics
Ideal for door modules, window lifters, and seat controllers where low-speed, cost-effective communication is required.
Automotive Lighting
Used in headlight leveling and interior ambient lighting control systems to link sensors and actuators to the main ECU.
Climate Control
Manages communication between the HVAC control unit and various vent flap motors or temperature sensors.
Switch Panels
Connects steering wheel buttons and center console switch matrices to the vehicle's body control module.

Getting Started

To evaluate this transceiver, designers can use the TLIN1039EVM evaluation module. Implementation requires connecting the TXD and RXD pins to a microcontroller UART and providing a VSUP supply between 4.5V and 36V. Ensure the PCB layout includes proper decoupling on the VSUP pin and minimizes trace length for the LIN bus line to reduce EMI.
