    MIC2544A/2548A
    Programmable Current Limit
    High-Side Switch General Description Features The MIC2544A and MIC2548A are integrated, high-side
    power switches optimized for low loss DC power switching
    and other power management applications, including
    Advanced Configuration and Power Interface (ACPI).
    The MIC2544A/48A is a cost-effective, highly integrated
    solution that requires few external components to satisfy
    USB and ACPI requirements.
    Load current management features include a precision
    resistor-programmable output current-limit and a soft-start
    circuit which minimizes inrush current when the switch is
    enabled. Thermal shutdown, along with current-limit,
    protects the switch and the attached device.
    The MIC2544A/48A’s open-drain flag output is used to
    indicate current-limiting or thermal shutdown to a local
    controller. The MIC2548A has an additional internal latch
    which turns the output off upon thermal shutdown
    providing robust fault control. The enable signal is
    compatible with both 3V and 5V logic, and is also used as
    the thermal shutdown latch reset for the MIC2548A
    The MIC2544A and MIC2548A are available in active-high
    and active-low enable versions in the 8-pin SOIC ...
