作为与VCM（音圈马达）匹配的driverIC（FP5510）一直被产业链当做一个小器件，故而默默无闻，较少为人所认知和谈论。其实小小的driverIC（FP5510），是摄像模组实现自动对焦功能不可或缺的一部分。与VCM马达是马车与车夫的关系。目前Closeloop(闭环式)异军突起、OIS呼之欲出。担当马车夫的driverIC（FP5510）日益显得重要，成为业界开始关注的焦点。10-BitDAC120mAVCMDriverwithI2CInterface（FP5510）TheFP5510isasingle10-bitDACwith120mAoutputcurrentvoicecoilmotor(VCM)driver,withanI2C-compatibleserialinterfacethatoperatesatclockratesupto400kHz.Itssupplyoperatesfrom2.3Vto3.6V.TheFP5510incorporateswithapower-onresetcircuit,power-downfunction.Power-onresetcircuitensurewhensupplypowerup,DACoutputisto0Vuntilvalidwritebitvaluetakesplace.Inpowerdownmode,thesupplycurrentisabout1μA.TheFP5510isdesignedforautofocusoperationincludesdigitalcameramodule,opticalzoomcameraphonesandlensautofocus.TheI2CaddressofFP5510is0x18h.TheFP5510withWLCSPpackagewhichitissuitableforreduced-spacemountinginmobilephoneandotherportableapplicati***。FeaturesPowerSupplyVoltageRang:2.3Vto3.6VVCMDriverforAuto-Focus10-BitResolutionCurrentSinkingof120mAforVCM2-WireI2CInterface(1.8VInterfaceCompatible)Internal4SlopeControlMechani***1.EnhanceSlopeControlMode2.OneStepMode3.LinearSlopeMode4.TwoStepSlopeModePower-S***eModeCurrent<1μAPowerOnReset(POR)***allSize:0.7mm×1.1mm(6-BallsWLCSP)Applicati***DigitalCameraModuleCellPhoneLensCoverWebCamera)
