Working Principles

ADM803RAKS-REEL7 works by continuously monitoring the supply voltage connected to the VCC pin. When the voltage drops below the specified threshold, the IC triggers the RESET pin, generating an active-low reset signal. This signal can be used to reset the system or trigger specific actions based on the application requirements. The timeout period, if configurable, determines how long the reset signal remains active after the voltage returns to an acceptable level.
