为提高高有效性系统的可靠度，明智的方法是去监测功率分布网络的健康和完整性。这些系统一般用于热插拔控制器中以限制冲击电流。由于所有卡上的功率由冲击控制电路输入，加入监测功能则顺其自然。为监测功率，这些电路也可用于检测冗余供电网络的完整性。advertisementProtectingandMonitoringHotSwappableCardsinHighAvailabilitySystems……

LTC4223定位于ATCA和MicroTCA系统中高级插拔卡热转换控制的简化。在5mm×4mm封装中通过控制布局大小和辅助功率，使其完全符合所有的MicroTCA的要求。单个卡监测和控制功能简化了LTC4223的状态和控制线。HotSwapSolutionMeetsAMCandMicroTCAStandardsDesignNote437VladimirOstrerovIntroductionTheLTC4223monitors12VloadcurrentbysensingTheLTC4223isadualHotSwapcontrollerthatmeetsvoltageacrossanexternalresistorandoutputsaground-thepowerrequirementsoftheMicroTelecommunicationreferencedvoltage(atthe12IMONpin)proportionaltoComputingArchitecture(MicroTCA)specicationrecentlytheloadcurrent.Italsoprovidesseparatepower-goodratiedbythePCIIndustrialComputerManufacturersoutputsforthetwosuppliesandasingle,commonfaultGroup(PICMG).……
