Working Principles

The S-8261AAMMD-G2MT2U is designed to monitor the supply voltage and provide a reset signal when it falls below a certain threshold. It operates based on the principle of comparing the input voltage with an internal reference voltage. When the supply voltage drops below the detection threshold, the output pin (OUT) is activated, indicating a low voltage condition. The built-in delay circuit ensures that the reset signal remains active for a specific period to allow the system to stabilize before resuming normal operation.
