  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.
