Working Principles

ADM1817-R23AKS-RL7 works by continuously monitoring the supply voltage using an internal voltage reference. When the voltage falls below the threshold, the reset output is activated, indicating a low-voltage condition. The reset signal remains active for a programmable timeout period after the voltage rises above the threshold, ensuring stability during power-up. The manual reset input allows for an external reset signal to override the internal monitoring circuit.
