```

---

| | --| VCC |-- --| GND |-- --| MR |-- --| RESET |-- --| VOUT |-- --| GND |-- --| VCC |-- |_______| ```

Pin Description: - VCC: Power supply input - GND: Ground reference - MR: Manual reset input (active-low) - RESET: Reset output - VOUT: Voltage monitor output

Functional Features

1. Voltage Monitoring: ADM707AR-REEL continuously monitors the input voltage level.
2. Reset Signal Generation: When the voltage falls below the set threshold, the IC generates a reset signal.
3. Adjustable Threshold: The reset threshold can be adjusted using external resistors to suit specific requirements.
4. Manual Reset: The manual reset input allows for an immediate system reset when triggered.
5. Power-On Reset Delay: The IC provides a delay before generating the reset signal after power-up, ensuring stable operation.

Advantages and Disadvantages

Advantages

• Reliable voltage monitoring and reset functionality
• Low power consumption
• Wide operating voltage range
• Adjustable reset threshold for flexibility
• Compact SOIC package for space-constrained applications

Disadvantages

• Limited pin count may restrict additional functionalities
• Requires external resistors for threshold adjustment

Working Principles

ADM707AR-REEL operates by comparing the input voltage with the set threshold voltage. When the input voltage drops below the threshold, the IC triggers the reset output, which can be used to reset the microcontroller or other digital circuitry. The reset signal remains active until the input voltage rises above the threshold again.
