產品型號:AS5145產品廠商:AMS產品封裝:16-LEADSOIC產品包裝:500PCS/盤產品類型:高分辨率磁性旋轉編碼IC產地:奧地利產品說明:AS5145磁性旋轉編碼器IC是一款非接觸式的完整系統級芯片,可在一圈360 范圍內提供分辨率達0.0879 的精確角度測量,即每轉4,096個位置。使用一個簡單的串行接口或PMW信號即可讀取該數字角度數據。另外,該器件采用改進的插值算法,可實現增量正交輸出模式,并能永久性編程為10位至12位分辨率。由于具有更佳的噪聲特性,精度進一步得到提升。除了支持用戶化零位編程、芯片ID和幫助磁鐵正確定位的診斷功能等奧地利微電子編碼器系列的所有標準功能外,AS5145還能提供一種與外部電路同步的特殊功能,以及正弦/余弦數字輸出模式。當該模式激活時,將輸出16位正弦和16位余弦雙通道數字數據,并在外部進行精確計算。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)
