    MIC2545A/2549A
    Programmable Current-Limit
    High-Side Switch General Description Features The MIC2545A and MIC2549A 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
    MIC2545A/49A 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 adjustable currentlimit, protects the switch and the attached device.
    The MIC2545A/49A’s open-drain flag output is used to
    indicate current-limiting or thermal shutdown to a local
    controller. The MIC2549A 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 MIC2549A.
    The MIC2545A and MIC2549A are available in active-high
    and active-low enable versions in 8-pin DIP, SOIC, and
    TSSOP packages. ...
