Working Principles

The ADM708ARMZ is a voltage supervisor IC that monitors the supply voltage of a system. It compares the supply voltage against a preset threshold and generates an active-low reset signal when the voltage drops below the threshold. The reset signal remains active until the supply voltage rises above the threshold and a timeout period elapses.

Detailed Application Field Plans

The ADM708ARMZ is commonly used in various applications, including:

1. Microcontroller Systems: Ensures proper initialization and reliable operation of microcontrollers.
2. Industrial Control Systems: Provides voltage supervision for critical control systems.
3. Automotive Electronics: Monitors power supply integrity in automotive electronic systems.
4. Battery-Powered Devices: Protects battery-powered devices from operating at low voltages.
5. Embedded Systems: Offers voltage monitoring capabilities for embedded systems.

Alternative Models
