Working Principles

The S-80844CLNB-B65T2U operates by comparing the input voltage (VDD) with the internally set threshold voltage. When the input voltage falls below the threshold, the reset output (RESET) becomes active low, indicating a voltage drop or power loss. The built-in delay circuit ensures that the reset signal remains stable for a specified duration (100ms) to prevent false triggering.
