    MIC2544/48
    Programmable Current-Limit High-Side Switch
    Features General Description The MIC2544 and MIC2548 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 MIC2544/48 are cost-effective, highly
    integrated solutions that require few external
    components to satisfy USB and ACPI requirements. 2.7V to 5.5V Input
    Adjustable Current-Limit up to 1.5A
    Reverse Current Flow Blocking (No “Body Diode”)
    75 ОјA Typical On-State Supply Current
    1 ОјA Typical Off-State Supply Current
    120 mΩ Maximum On-Resistance
    Open-Drain Fault Flag
    Thermal Shutdown
    Thermal Shutdown Output Latch (MIC2548)
    2 ms (Slow) Turn-On and Fast Turn-Off
    Available with Active-High or Active-Low Enable Applications Load current management features include a precision
    resistor-programmable output current-limit and a
    soft-start circuit that minimizes inrush current when the
    switch is enabled. Thermal shutdown, along with
    current-limit, protects the switch and the attached ...
