    Single-Channel, Negative High-Voltage Hot
    Swap Power Controllers General Description Features The MIC2588 and the MIC2594 are single-channel, negative-voltage hot swap controllers designed to address the
    need for safe insertion and removal of circuit boards into
    “live” high-voltage system backplanes, while using very few
    external components. The MIC2588 and the MIC2594 are
    each available in an 8-pin SOIC package and work in conjunction with an external N-Channel MOSFET for which the
    gate drive is controlled to provide inrush current limiting and
    output voltage slew-rate control. Overcurrent fault protection
    is also provided and includes a programmable overcurrent
    threshold. During an output overload condition, a constantcurrent regulation loop is engaged to ensure that the system
    power supply maintains regulation. If a fault condition exceeds
    a built-in 400Вµs nuisance-trip delay, the MIC2588 and the
    MIC2594 will latch the circuit breaker’s output off and will
    remain in the off state until reset by cycling either the UV/OFF
    pin or the power to the IC. A master Power-Good signal is
    provided to indicate that the output voltage of the soft-start
    circuit is within its valid output range. This signal can be used
    to enable one or more DC-DC converter modules.
