MIC2586-1BM集成電路（IC）的熱插拔控制器規(guī)格書PDF中文資料

General Description

The MIC2586 and MIC2586R are single-channel positive voltage hot swap controllers/sequencers designed to provide safe insertion and removal of boards for systems that require live (always-powered) backplanes. These devices use few external components and act as controllers for external N-channel power MOSFET devices to provide inrush current control and output voltage slew rate control. Overcurrent fault protection is provided via programmable analog foldback current limit circuitry equipped with a programmable overcurrent filter.
