2. GND: Ground reference
3. RESET: Output signal indicating the status of the monitored voltage level

Functional Features

• Monitors the voltage level and generates a reset signal when it falls below the specified threshold.
• Provides a stable reset output during power-up and power-down conditions.
• Offers a manual reset input for external control.
• Low quiescent current consumption ensures minimal power usage.

Advantages and Disadvantages

Advantages

• Wide supply voltage range allows compatibility with various systems.
• Small package size enables space-saving integration into compact designs.
• Low-power operation prolongs battery life in portable devices.
• Reliable voltage monitoring prevents system malfunction due to unstable power supply.

Disadvantages

• Limited reset timeout period may not be suitable for applications requiring longer delay times.
• Lack of adjustable reset threshold voltage restricts customization options for specific requirements.

Working Principles

ADM1813-5ART-RL7 operates based on a voltage comparator circuit. It continuously monitors the input voltage and compares it with the preset threshold voltage. When the input voltage drops below the threshold, the reset output is activated, indicating a low-voltage condition. The reset signal remains active until the voltage rises above the threshold or a manual reset is triggered.
