Working Principles

The S-80845CLY-Z2-U operates by continuously monitoring the input voltage (VDD) against a preset threshold voltage. When the voltage drops below the threshold, the reset output (RESET) becomes active low, indicating a voltage failure or power-on reset condition. The built-in delay time prevents false resets caused by temporary voltage fluctuations or noise.
