Working Principles

The ADM696AR monitors the power supply voltage using an internal voltage reference and comparator. When the voltage falls below the specified threshold, the reset output is activated, generating a reset signal. The reset signal remains active for the duration set by the reset timeout period. Additionally, the manual reset input allows for immediate system reset when triggered.
