MAX1838 Dual USB Switch with Fault Blanking and Autoreset General Description
... The MAX1838 monitors the output to detect an overload condition. If an output fault is detected for more than the 20ms blanking time, OUT_ latches, FAULT goes low, and OUT sources 25mA to the load. If the voltage at OUT exceeds 0.5V for 20ms, the fault resets, the 25mA current source shuts down, and ...
