应对供电线路错误的理想二极管保护

在双电源供电应用中，供电连接可能被错误地连接，这可导致负载受到损坏。采用LTC4355和LTC44354构成的理想二极管保护方案可提供类似于肖特基二极管的保护模式，但具有更低的功耗，并且布局紧凑、效率提高。IdealDiodesProtectAgainstPowerSupplyWiringErrorsDesignNote444MeilissaLumIntroductionsucherrors.WiringerrorscouldincludereversepolarityHighavailabilitysystemsoftenemploydualfeedpowerorcross-feedconnections.Knowingthis,circuitdesign-distributiontoachieveredundancyandenhancesystemersareaccustomedtousingdiscretediodesolutionstoreliability.ORingdiodesjointhefeedstogetherattheprotectagainstsuchmishaps.Itisimportantthatactivepointofload,mostoftenusingSchottkydiodesforlow
