摘要：某些类型的负载在启动过程中需要更多的电流比运行时。其他负载可以被限制在一个较低的功耗在启动电流，但需要较高的工作电流。本文介绍了一种自动调整电源电路的过流保护水平或启动完成后的应用电路。Maxim>DesignSupport>TechnicalDocuments>ApplicationNotes>CircuitProtection>APP4872Maxim>DesignSupport>TechnicalDocuments>ApplicationNotes>Hot-SwapandPowerSwitchingCircuits>APP4872Maxim>DesignSupport>TechnicalDocuments>ApplicationNotes>Power-SupplyCircuits>APP4872Keywords:hot-swap,hot-plug,power,switch,MOSFET,high-side,inrush,protection,fuse,circuit-breaker,startup,precharge,integrated,soft-switch,loadOct28,2010APPLICATIONNOTE4872ProtectYourIntegrated-FETPowerSwitcheswithAutomaticCurrent-LimitAdjustmentBy:DwightLarson,SeniorMemberoftheTechnicalStaffOct28,2010Abstract:Somety……

摘要：由于内部断路器延迟和有限的MOS栅极下拉电流，许多热插拔控制器不限制在第一个10μs到50μs的电流后，输出短路。结果可以是一个简短的几百安培流动。一个简单的外部电路计数器这个问题，最大限度地减少初始电流尖峰和终止内为200ns至500ns短路。Maxim>AppNotes>AMPLIFIERANDCOMPARATORCIRCUITSCIRCUITPROTECTIONHOT-SWAPANDPOWERSWITCHINGCIRCUITSKeywords:hot-swapcontrollers,inrushcurrent,circuitprotection,short-circuitcurrentAug27,2004APPLICATIONNOTE3328MinimizeShort-CircuitCurrentPulseinHot-SwapControllerAbstract:Becauseofinternalcircuit-breakerdelayandlimitedMOS-gatepulldowncurrent,manyhot-swapcontrollersdonotlimitcurrentduringthefirst10sto50sfollowingashortedoutput.Theresultcanbeabriefflowofseveralhundredamperes.Asimpleexternalcircuitcountersthisproblembyminimizingtheinitialcurrentspikeandterminatingtheshortcircuitwithin200nsto500ns.Atypical+12V,6A,hot-swapcontrollercircuit(Figure1)contains(like……
