    MIC2546/2547
    Dual Programable Current Limit Switch General Description Features The MIC2546 and MIC2547 are integrated high-side dual 2.7V to 5.5V input
    power switches optimized for low loss dc power switching Adjustable current-limit up to 1.5A
    and other power management applications, including Reverse current flow blocking (no “body diode”)
    Advanced Configuration and Power Interface (ACPI). The 100ОјA typical on-state supply current per channel
    MIC2546/47 is a cost-effective, highly integrated solution 2ОјA typical off-state supply current
    that requires few external components to satisfy USB and
    ACPI requirements. 120mΩ maximum on-resistance
    Load current management features include a precision Open-drain fault flag
    resistor-programmable output current-limit and a soft-start Thermal shutdown
    circuit which minimizes inrush current when the switch is Thermal shutdown output latch (MIC2547)
    enabled. Thermal shutdown, along with current-limit, 2ms (slow) turn-on and fast turnoff
    protects theswitch and the attached device. Available with active-high or active-low enable
    The MIC2546/47’s open-drain flag outputs are used to
    indicate current-limiting or thermal shutdown to a local
    controller. The MIC2547 has an additional internal latch
    Applications
    which turns the output off upon thermal shutdown
    providing robust fault control. The enable signal is USB power distribution
    compatible with both 3V and 5V logic, and is also used as PCI Bus Power Switching
    the thermal shutdown latch reset for the MIC2547. Notebook PC
    The MIC2546 and MIC2547 are available in active-high ACPI power distribution
    and active-low enable versions in 16-pin TSSOP and SOP PC card hot swap applications ...
