Create Robust Automotive Designs withNational’s High-Quality Automotive SolutionsNational Semiconductor, a leader in integrated circuitsand a leading-edge silicon supplier in the automotiveindustry, offers a diverse product portfolio to address themany challenges and needs of the automotive market.Today’s automotive applications require reliabilityand precision under high temperature environmentsand wide operating voltage ranges. At the sametime, high efficiency solutions are critical to helpingautomotive electronic systems capitalize on space,lower operating temperatures, and conserve on overallpower consumption. National offers a diverse portfolioof data converter, temperature sensor, amplifier, powermanagement, audio, and interface products to addresseveryday design challenges of the automotive industry.Power Management SolutionsEfficiency in automotive solutions can not only saveelectrical power, but can also lower operating junctiontemperature and reduce solution size. National offersbest-in-class, low Iq products that preserve battery life foralways-on electronics along with a wide selection ofLDOs, LED drivers, and PowerWise ® regulators forsystems with high-efficiency needs. Additional featuressuch as wide input voltage ranges, adjustable frequencies,and other special features make National’s power managementsolutions ideal for automotive systems.SerDes SolutionsElectronic complexities in today’s cutting-edge vehiclesintroduce more variables for failure. National’s FPD-link IIsolutions simplify systems or improve robustnessusing true embedded clock architecture for lower systemcost, several industry-leading EMI mitigation techniques,and a Built-In Self Test (BIST) feature for performingdiagnostic functions to ensure signal integrity.Data Conversion SolutionsA wide portfolio of general purpose and high-speed analogto-digitalconverters (ADCs) are ideal for applications likeGPS and adaptive cruise control. National’s ADCs maintainhigh dynamic performance over varying automotive temperatureranges while keeping system power dissipation low.Audio SolutionsNational’s audio products enable high-performancelistening experiences in vehicles with high-fidelityproducts, and minimize EMI with spread spectrum andedge rate control Class D products. These innovativesolutions allow for multiple features in a single device,while reducing cable and heat sink requirements, forsmaller, lighter automotive systems.Temperature Sensor SolutionsIncreased electronic content in critical automotiveapplications is driving the need for specialized hightemperature thermal management solutions. As a pioneerin this area, National’s extensive line of thermal productsinclude innovative technology building blocks that offer thehighest accuracy, lowest power, and smallest packageswith built-in safety mechanisms. This promotes the highestlevels of reliability and best-in-class energy efficientsolutions over a wide range of temperatures.Current Sensor SolutionsNational’s current sensors are optimized for automotiveuse and are 100 % tested at high and low temperatures toensure consistent accuracy.Amplifier SolutionsIn many automotive analog applications and subsystems,EMI is a concern for the system designer. EMI mayinterrupt, alter, or limit the effective signal performance ofa critical electronic control unit or a car radio application.National offers EMI-hardened amplifiers which suppressthe interference and enhanced connectivity caused byEMI sources. As a result, these amplifiers minimize theneed for adding filtering or costly shielding components.PowerWise ® Solutions for Energy-Efficient DesignsNational’s energy efficientPowerWise solutions for automotiveproducts allow automotive designersto reduce heat wear on electronics for longer servicelife while minimizing the overall power consumption.See all of National’s automotive applications, products, andPowerWise solutions at: www.national.com/automotive
Automotive-Grade ProductsNational has developed Automotive-Grade products to help address and streamline design challenges withproducts that have passed rigorous testing and provide enhanced reliability specific to automotive requirements.Automotive-Grade ProductsNational’s Automotive-Grade products are:• AEC-Q100 with capabilities for each temperature grade• TS-16949 certified• Meeting customer-specific requirements• Visible and traceable throughout themanufacturing, ordering, and supply chain processesProduct QualificationAlong with the AEC-Q100 reliability specification, acomplete Production Part Approval Process (PPAP)package, compliant with the AIAG manual, is generatedbased on customer specifications.Product DevelopmentA comprehensive, phase review based developmentprocess ensures quality from product inception throughcompletion. This process includes complete designprocess documentation and AEC-Q003-compliant devicecharacterization.Manufacturing QualityBeyond AEC-Q100 certification, National’s manufacturingprocess distinguishes its Automotive-Grade products fromothers with:• Special manufacturing flow with increased inspectionand screening• Enhanced defect detection through methods includingPAT, delta current stress tests, statistical bin yieldanalysis, and reliability monitors• Statistical process control• Defect analysis using a closed loop, 8D-basedcorrective action and 5 Why root cause analysisChange ManagementTo provide better visibility into product changes, Nationalprovides notifications with complete AEC-QXXXcompliant documentation, including:• Six months notification for change management• Twelve month end-of-life notification with threemonthshipping windowIdentifying Automotive-Grade Products in this GuideAll products featured in this guide are ideal for designingautomotive applications.To find products that are fully Automotive Grade compliant,look for the symbol. Products with a ■ symbol arecompleting the requirements for Automotive Grade statusand will be fully qualified within the next 6 months.Unique Device IdentificationEach part is identified by a special order code ‘Q’ in thedevice part number. This identification enables completeproduct visibility and traceability throughout the ordering,manufacturing and supply chain.AECQ temp grades are as follows:Temperature Grade Min (°C) Max (°C)Grade 0 -40 +150Grade 1 -40 +125Grade 2 -40 +105Grade 3 -40 +85Grade 4 -0 +70Visit www.national.com/automotive for the most currentlist of AEC-Q100-qualified products.www.national.com/automotivepower.national.com 3
