Working Principles

The ADM708ARZ monitors the supply voltage of a system using an internal voltage reference. When the supply voltage falls below the programmed threshold voltage, the reset output becomes active-low, indicating a system reset condition. The reset output remains low until the supply voltage rises above the threshold voltage and the reset timeout period elapses.

Detailed Application Field Plans

The ADM708ARZ is commonly used in various electronic systems where reliable voltage monitoring and system reset functionality are required. Some application fields include:

1. Microcontrollers: Ensuring proper operation by monitoring the power supply voltage.
2. Industrial Control Systems: Providing reset signals to restart the system in case of power fluctuations.
3. Automotive Electronics: Preventing malfunctions by monitoring the battery voltage.
4. Medical Devices: Ensuring safe operation by monitoring critical power supply voltages.
5. Communication Systems: Resetting the system in case of power interruptions or voltage drops.
