Working Principles

MIC3808BMM-TR operates by comparing the input voltage (TH) with a reference voltage. If the input voltage exceeds the threshold, the output (OUT) is pulled low, indicating an overvoltage condition. Similarly, if the input voltage falls below the threshold, the output is pulled low, indicating an undervoltage condition. The manual reset input (MR) allows for a forced reset, overriding the automatic reset function.
