Working Principles

The S-80955CNPF-G9RTFG operates by continuously monitoring the input voltage level. When the voltage falls below the preset threshold, the output pin generates a low signal, indicating a voltage drop. This signal can be used to trigger a reset sequence or perform other necessary actions to ensure proper device functionality. The built-in delay circuit prevents false triggering by providing a stable reset signal only after the voltage has returned to the normal range.
