Working Principles

The S-80849CLY-B2-U operates based on the principle of comparing the input voltage (VIN) with a reference voltage (VDET). When VIN exceeds VDET, the output (RESET) switches to a high state ("H"). Conversely, when VIN falls below VDET, the output switches to a low state ("L"). The built-in delay circuit ensures that the output remains stable for a specified time (200ms) after the voltage crosses the threshold.
