Working Principles

The S-8209AAT-T8T1U works by continuously monitoring the voltage level at the VDET pin. When the voltage drops below a predetermined threshold, the IC generates a reset signal at the RESET pin. The built-in delay circuit ensures that the reset signal remains stable for a specified time (200ms) before being released. This delay prevents premature system resets caused by temporary voltage fluctuations.
