LIN Bus Networking Solutions

LIN Bus Solutions Supporting Simple to Complex Designs

Low-cost Local Interconnect Network (LIN) systems are used throughout the automobile in comfort, powertrain, sensor, and actuator applications. Our modular LIN family ranges from simple transceiver ICs to complex system basis chips with a LIN transceiver, voltage regulator and watchdog. At higher integration levels, our System-in-Package (SIP) solutions feature an AVR®, PIC®  or Arm® Cortex® M0+ based SAM microcontroller (MCU), LIN transceiver, voltage regulator and watchdog in a single package.

LIN Bus Products

Stand-Alone LIN Transceivers

These devices provide the physical layer interface between a MCU and the LIN bus.

Parametrics

LIN Transceivers With Voltage Regulator

These devices combine the physical layer interface for LIN communication with a low-dropout voltage regulator, simplifying system design and reducing component count.

LIN Interface Functional Safety

The increasing complexity of functions in today’s cars is driving home the importance of functional safety standards. Driver assistance and safety systems in modern cars need robust and dependable electronic components. The safety risks resulting from random hardware failures or systematic hardware/software errors must be reduced as much as possible throughout the product’s foreseeable lifetime.

Our LIN products offer a variety of safety features to help you implement a more reliable motor control design.

    • The ATA6632/33/34 series of devices also provides a family footprint so you can upgrade your designs with various devices within this series

Software to Support Your LIN Application

One of our key design partners, IHR GmbH, has developed LIN-compliant drivers for the PIC16F, PIC18F and PIC24F families of microcontrollers.

IHR is one of the leading manufacturers of diagnosis and emulation tools, as well as gateways for the automotive industry. IHR GmbH is also an associated member of the LIN consortium and has been performing LIN conformance tests for LIN 1.3, LIN 2.0 and LIN 2.1 test specifications.

To further aid the user in configuring the driver for their end application, IHR has developed a LIN Configuration Tool. This tool helps automate the process of generating LIN-compliant code which contains bus configuration information, node information and signal data using the LIN Description File (LDF).
