    USB Power Controller General Description Features The MIC2012 is a dual channel USB power switch designed to
    support the power distribution requirements for USB Wakeup
    from the ACPI S3 state. The MIC2012 will directly switch its
    two outputs between a 5V main supply and a 5V auxiliary
    supply normally provided in ATX style power supplies.
    The MIC2012 will adjust its current-limit threshold according
    to the ACPI state it is in. In the normal active S0 state the current-limit is set at 500mA minimum per channel satisfying the
    USB continuous output current specification. In the S3 state
    the current-limit can be reduced to only 100mA per channel
    to minimize the current that is supplied by the auxiliary supply
    thereby ensuring that voltage regulation is maintained even
    during fault conditions.
    The MIC2012 provides make-before-break switching to ensure
    glitch-free transitions between the S3 and S0 states. Each
    channel is also thermally isolated from the other so that a
    fault in one channel does not effect the other. FAULT status
    output signals are also provided indicating overcurrent and
    thermal shutdown conditions.
    The MIC2072 option latches the output off upon detecting
    an overcurrent condition for more than 5ms minimum. The
    output can be reset by either toggling the EN inputs of the
    MIC2072-1, -2 or by removing the load. Latching the output ...
