General Description
The MIC2025 and MIC2075 are high-side MOSFET switches
optimized for general-purpose power distribution requiring
circuit protection.
The MIC2025/75 are internally current limited and have
thermal shutdown that protects the device and load. The
MIC2075 offers “smart” thermal shutdown that reduces cur-
rent consumption in fault modes. When a thermal shutdown
fault occurs, the output is latched off until the faulty load is
removed. Removing the load or toggling the enable input will
reset the device output.
Both devices employ soft-start circuitry that minimizes inrush
current in applications where highly capacitive loads are em-
ployed. A fault status output flag is provided that is asserted
during overcurrent and thermal shutdown conditions.
The MIC2025/75 is available in the MM8® 8-lead MSOP
and 8-lead SOP.

... FLG signal will continue to cycle on and off until the device is disabled or the fault is removed. Figure 2 depicts typical timing. If the MIC2075 goes into thermal shutdown, its output will latch off and a pull-up current source is activated. This allows the output latch to automatically reset when the load (such as a USB device) is removed ...

... This “soft- start” feature effectively isolates power supplies from highly capacitive loads by reducing inrush current during hot-plug events. Figure 3 shows how the MIC2075 may be used in a hot-plug application. In cases of extremely large capacitive loads (>400µF), the length of the transient due to inrush current may exceed the delay provided by the integrated filter ...
