摘要：复杂的电子设备测试变化很大，从最简单的类型——手动测试——到最复杂——大型自动测试设备（ATE）。在之间简单的手动测试和大规模ATE在于低预算和中型测试，是此应用程序说明的重点。这些类型的测试系统通常专用于测试特定的组件或电路，PC的控制之下。PC并行或串行端口提供了方便的连接pc机与小、成本敏感型应用程序。IEEE488总线可以方便地将电脑连接到多个的测试仪器，不可以通过并行或串行端口来完成。虽然它增加测试系统的价格，能力它为提供了一次到PC连接多个文书证明是正确的额外成本。在设计时为测试仪硬件，使用正确的设计技术，从一开始可以消除或最大限度减少很难解决的问题。Maxim>AppNotes>AUTOMATICTESTEQUIPMENT(ATE)GENERALENGINEERINGTOPICSINTERFACECIRCUITSPROTOTYPINGANDPCBOARDLAYOUTSENSORSIGNALCONDITIONERSKeywords:automatictestequipment,ATE,RS-232,GPIB,HPIB,faultprotected,signallineprotector,pressureJun29,2001sensor,signalconditioner,rs232APPLICATIONNOTE761AutomaticTestEquipmentonaBudgetAbstract:Thecomplexityofelectronic-devicetestingvarieswidely,rangingfromthesimplesttype―manualtesting―tothemostcomplex―large-scaleautomatictestequipment(ATE).Inbetweensimplemanualtestingandlarge-scaleATEliesthelow-budgetandmedium-scaletestingthatisthefocusofthisapplicationnote.Thesetypesoftestsystemsareusuallydedicatedtotestingaspecificcomponentorcircuit,underth……

摘要：MOSFET功率开关驱动器必须从电池反向连接保护。一个小的整流二极管可以防止逆转的电池，但这种做法是不可接受的一般系统中，电池的寿命是至关重要的。二极管的正向压降（0.6V至0.7V典型值）为6V电池，产生了约10％的恒功率的损失，这与日益减少的电池电压增加。比单二极管保护的改进。Maxim>AppNotes>BATTERYMANAGEMENTPOWER-SUPPLYCIRCUITSKeywords:MOSFETdriver,reversebatteryprotection,mosfet,reversebatteryprotected,powerswitchMay11,2003drivers,diodeprotectionAPPLICATIONNOTE2012MOSFETDriverIsReverse-BatteryProtectedAbstract:MOSFETpower-switchdriversmustbeprotectedfromareverse-batteryconnection.Asmallrectifierdiodecanprotectagainstreversedbatteries,butthatapproachisgenerallyunacceptableforsystemsinwhichbatterylifeiscrucial.Fora6Vbattery,thediode'sforwardvoltagedrop(0.6Vto0.7Vtypical)producesaconstantpowerlossofapproximately10%,whichincreaseswithdwindlingbatteryvoltage.Animprovementoversingle-diodeprotectionisshown.MOSFETpower-switchdriversmustbeprotected……
