Working Principles

The MIC812MU TR is a low voltage reset circuit that monitors the supply voltage of a system. When the supply voltage drops below the reset threshold voltage, the reset output is activated. The reset output remains active until the supply voltage rises above the reset threshold voltage for the specified timeout period. This ensures that the system is reset and remains in a reliable state during power-up or voltage fluctuations.
