描述 Description

The MIC2582 and MIC2583 are single-channel positive voltage hot swap controllers designed to allow the safe insertion of boards into live system backplanes. The MIC2582 and MIC2583 are available in 8-pin SOIC and 16-pin QSOP packages, respectively. Using a few external components and by controlling the gate drive of an external N-Channel MOSFET device, the MIC2582/83 provide inrush current limiting and output voltage slew rate control in harsh, critical power supply environments.Additionally, a circuit breaker function will latch the output MOSFET off if the current-limit threshold is exceeded for a determined period. The MIC2583R option includes an auto-restart function upon detecting an over current condition.
