    Single-Channel, Positive High-Voltage
    Hot Swap Controller
    Revision 2.0 General Description Features The MIC2587 and MIC2587R are single-channel positive
    voltage hot swap controllers 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 Nchannel 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. These protection circuits combine to limit
    the power dissipation of the external MOSFET to ensure
    that the MOSFET is in its SOA during fault conditions. The
    MIC2587 provides a circuit breaker function that latches
    the output MOSFET off if the load current exceeds the
    current limit threshold for the duration of the programmable
    timer. The MIC2587R provides a circuit breaker function
    that automatically attempts to restart power after a load
    current fault at a low duty cycle to prevent the MOSFET
    from overheating. Each device provides either an activeHIGH (-1YM) or an active-LOW (-2YM) “Power-is-Good”
    signal to indicate that the output load voltage is within
    tolerance of the application circuit’s design objective. MIC2587: Pin-for-pin functional equivalent to the
    LT1641 Operates from +10V to +80V with 100V ABS MAX ...
