Working Principles

The ADM8691ARN is a voltage supervisor IC that monitors the supply voltage of electronic systems. It compares the input voltage with a user-selectable threshold voltage and generates a reset signal when the voltage falls below the threshold. The timeout period can be adjusted to control the duration of the reset signal. The manual reset input allows for system initialization. The low quiescent current ensures minimal power consumption.
