... MIC2042 automatically resets its output and resumes supply- ing current to the load when the die temperature drops to 120°C. If the fault is still present, the MIC2042 will quickly re- heat and shut down again. This process of turning ON-OFF-ON is called thermal cycling and will continue as long as the power switch is enabled while the fault or excessive load is present ...
