Working Principles

The XC6119C21ANR-G operates based on a voltage divider network connected to the VDD pin. When the input voltage drops below the threshold level, the internal comparator triggers the reset output to go low. The built-in delay circuit ensures that the reset signal remains low for a specified time period before returning to its normal state.
