Working Principles

The S-80845CNUA-B86T2G operates based on a voltage divider network connected to the VDET pin. The internal comparator compares the divided voltage with a reference voltage to determine if it falls within the detection range. If the voltage drops below the threshold, the RESET pin is activated, generating a reset signal. The built-in delay circuit ensures the reset signal remains active for a specific duration, preventing false resets due to temporary voltage fluctuations.
