Working Principles

The MIC1232N is designed to monitor the supply voltage of a system. It continuously compares the voltage at the TH terminal with a precise internal reference voltage. If the supply voltage drops below the threshold voltage, the reset output is activated, indicating a power failure or an out-of-range condition.

The timeout feature ensures that the reset signal remains active for a minimum period of 140ms after the supply voltage returns to normal. This prevents false resets caused by short power interruptions or voltage fluctuations.
