Working Principles

The S-80945CNMC-G9FT2G operates by comparing the input voltage (VDET) with the internally set threshold voltage. When the input voltage falls below the threshold, the voltage detection output (VOUT) becomes active low, indicating a voltage drop. The built-in delay circuit ensures stable operation by preventing false triggering due to temporary voltage fluctuations.
