Working Principles

ADM810RAKSZ-REEL7 works based on a voltage comparator circuit. It compares the power supply voltage with the specified threshold voltage. When the voltage drops below the threshold, the reset output is activated. The reset signal remains active for a defined timeout period after the voltage rises above the threshold. This ensures that the microcontroller or digital circuitry starts operating only when the power supply voltage stabilizes.
