摘要：本应用指南中解决了一个很常见的问题，为汽车的电子控制单元(ECU)的只有3.3V电源供电。ISO118982标准规定只有5V电源供应权力铁路可以收发器。本文说明如何可以提供汽车可以收发器与3.3V电荷泵提供低功耗、低--以和容易解决此问题。通过消除在5V电源线，许多汽车Oem将节省重量和成本，同时提高里程性能。文章还讨论了对电磁辐射（电磁辐射）和免疫(EMI)和电磁兼容(EMC)的电路的影响。MAX13041可以收发器每次应用程序中的MAX1759充电泵。Maxim>AppNotes>AutomotiveInterfaceCircuitsKeywords:3VCAN,CAN,CANTransceivers,TJA1041,TJA1040,TJA1050,PCA82C250,TLE625,CANBUS,Automotivenetworks,Dec06,2010AutomotiveCAN,HighESD,lowpowerCANAPPLICATIONNOTE4643AchieveISO11898-2-Compliant5VHS-CANCommunicationfroma3.3VSupplyAbstract:Thisapplicationnotesolvesaverycommonproblemofpoweringanautomotiveelectroniccontrolunit(ECU)withonlya3.3Vsupply.TheISO11898-2standardstipulatesthatonlya5VpowersupplyrailpowerstheCANtransceiver.ThisarticleshowshowanautomotiveCANtransceivercanbesuppliedwitha3.3Vchargepumptoprovidealowpower,low-voltage,andeasysolutiontothisproblem.Byeliminatingthe5Vpowerrail,manyautomotiveOEMswillsaveweighta……
