    Single Channel, High Current, Low Voltage,
    Protected Power Distribution Switch General Description Features The MIC2042 and MIC2043 are high-side MOSFET switches
    optimized for general purpose power distribution applications
    which require circuit protection. The devices switch up to 5.5V
    and as low as 0.8V while offering both programmable current
    limiting and thermal shutdown to protect the device and the
    load. A fault status output is provided in order to detect
    overcurrent and thermal shutdown fault conditions. Both
    devices employ soft-start circuitry to minimize the inrush
    current in applications that employ highly capacitive loads.
    Additionally, for tighter control over inrush current during
    start-up, the output slew-rate may be adjusted by an external
    capacitor.
    The MIC2043 features a auto-reset circuit breaker mode that
    latches the output off upon detecting an overcurrent condition
    lasting more than 28ms. The output is reset by removing or
    reducing the load.
