    MIC2039
    High-Accuracy, High-Side, Adjustable
    Current Limit Power Switch General Description Features The MIC2039 is a high-side MOSFET power distribution
    switch providing increased system reliability by using 5%
    current-limit accuracy. The MIC2039 has an operating input voltage range from
    2.5V to 5.5V, is internally current limited, and has thermal
    shutdown to protect the device and system. The MIC2039
    is offered with either active-high or active-low logic level
    enable input controls. It has an open drain fault status
    output flag with a built-in 32ms delay that asserts low
    during overcurrent or thermal-shutdown conditions.
    The MIC2039 switches feature an adjustable output
    current limit that is resistor programmable from 0.2A to
    2.5A. The MIC2039 switch also offers a unique, Kickstart
    feature that allows momentary high-current surges up to
    the secondary current limit (ILIMIT_2nd) during startup or
    while operating in steady state. This is useful for charging
    loads with high inrush currents, such as capacitors. After
    an overcurrent condition is established, these switches
    enter into a constant current-limit mode unless the die
    temperature exceeds the thermal-shutdown specification.
    The MIC2039 is available in 6-pin SOT-23 and 6-pin
    2mm Г— 2mm thin DFN packages. The MIC2039 has an ...
