    Single Channel, High Current, Low Voltage,
    Protected Power Distribution Switch General Description Features The MIC2044 and MIC2045 are high-side MOSFET switches
    optimized for general purpose power distribution applications
    that require circuit protection. These 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 to indicate
    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 MIC2045 features a auto-reset circuit breaker that latches
    the output OFF upon detecting an overcurrent condition
    lasting more than 32ms. The output is reset by removing or
    reducing the load.
