... The MIC2073/2074 are high-side MOSFET switches optimized for general-purpose power distribution requiring circuit protection. The MIC2073/2074 are internally current limited and have thermal shutdown for protecting the device and load. The MIC2074 offers “smart” shutdown that reduces current consumption in fault mode. When a fault occurs due to thermal shutdown, the output is latched off. MIC2074s’ ...

... USB device) is removed. The output can also be reset by toggling EN. Refer to Figure 1 for timing details. The MIC2073 will automatically reset its output when the die temperature cools down to 120°C. The MIC2073 output and FLG signal will continue to cycle on and off until the device is disabled or the fault is removed ...
