产品型号:AS5145产品厂商:AMS产品封装:16-LEADSOIC产品包装:500PCS/盘产品类型:高分辨率磁性旋转编码IC产地:奥地利产品说明:AS5145磁性旋转编码器IC是一款非接触式的完整系统级芯片,可在一圈360 范围内提供分辨率达0.0879 的精确角度测量,即每转4,096个位置。使用一个简单的串行接口或PMW信号即可读取该数字角度数据。另外,该器件采用改进的插值算法,可实现增量正交输出模式,并能永久性编程为10位至12位分辨率。由于具有更佳的噪声特性,精度进一步得到提升。除了支持用户化零位编程、芯片ID和帮助磁铁正确定位的诊断功能等奥地利微电子编码器系列的所有标准功能外,AS5145还能提供一种与外部电路同步的特殊功能,以及正弦/余弦数字输出模式。当该模式激活时,将输出16位正弦和16位余弦双通道数字数据,并在外部进行精确计算。DescriptionTheAS5145isacontactlessmagneticrotaryencoderforaccurateangularmeasurementoverafullturnof360 .Itisasystem-on-chip,combiningintegratedHallelements,analogfrontendanddigitalsignalprocessinginasingledevice.Tomeasuretheangle,onlyasimple2-polemagnet,rotatingoverthecenterofthechip,isrequired.ThemagnetmaybeplacedaboveorbelowtheIC.Theabsoluteanglemeasurementprovidesinstantindicationofthemagnetsangularpositionwitharesolutionof0.0879 =4096postitionsperrevoloution.ThisdigitaldataisavailableasaserialbitstreamandasaPWMsignal.AninternalvoltageregulatorallowstheAS5145tooperateateither3.3Vor5Vsupplies.KeyFeatures Contactlesshighresolutionrotationalpositionencodingoverafullturnof360 2digital12-bitabsoluteoutputs:SerialinterfaceandPulseWidthModulated(PWM)outputs3incrementaloutputsQuadratureA/B(10or12bit)andIndexoutputsignalUserprogrammablezeropositionFailuredetectionmodeformagnetplacementmonitoringandlossofpowersupply Red-Yellow-Green indicatorsdisplayplacementofmagnetinZ-axisSerialread-outofmultipleinterconnectedAS5145devicesusingDaisyChainmodeToleranttomagnetmisalignmentandarigapvariationsWidetemperaturerange:-40 Cto 150 CFullyautomotiveAEC-Q100qualified,grade0SmallPb-freepackage:SSOP16(5.3mmx6.2mm)
