... VIN ILIM 5 6 VBIAS MIC2040/MIC2041 10-Pin MSOP (MM) Pin Function Switch Enable Input: Gate control pin of the output MOSFET available as an active high (–1) or active low (–2) input signal. Fault Status Output: Open drain N-Channel device, active low. This pin indicates an overcurrent, or thermal shutdown condition. For an overcurrent event, /FAULT is asserted if the duration of the overcurrent condition lasts longer than 28ms ...

... The MIC2041 is equipped with an internal circuit breaker for overcurrent protection. During an overcurrent event which exceeds the flag delay, the /FAULT output is asserted and the MIC2041 latches the output off. Once the overcurrent load is removed, the output automatically resets. Current Limit vs. R SET 2 ...

... MOSFET being shut off. Circuit Breaker Function (MIC2041) The MIC2041 is designed to shut off all power to the load when a fault condition occurs, just as a circuit breaker would do. A fault condition is deemed to be anytime the output current exceeds the current limit for more than the flag delay period, nominally 28ms ...
