Working Principles

The S-80948CNMC-G9JT2U operates by continuously monitoring the input voltage (VIN) and comparing it to the selected detection voltage threshold. When the input voltage falls below this threshold, the reset output (RESET) is activated, indicating a low voltage condition. The built-in delay circuit ensures that the reset signal remains active for the specified delay time before returning to its inactive state.
