1. VCC: Power supply input pin.
2. GND: Ground reference pin.
3. RESET: Output pin that indicates the status of the monitored voltage.

Functional Features

1. Voltage Monitoring: ADM809JAKSZ-REEL continuously monitors the input voltage and provides a reset signal when it falls below the specified threshold.
2. Adjustable Reset Threshold: The reset threshold voltage can be adjusted to suit different system requirements.
3. Manual Reset Input: An active-low manual reset input allows for external control of the reset function.
4. Power-On Reset Delay: The device ensures a stable power supply before releasing the reset signal, preventing premature system operation.

Advantages and Disadvantages

Advantages

• Low power consumption makes it suitable for battery-powered applications.
• Wide operating voltage range allows for compatibility with various systems.
• Precision voltage monitoring ensures accurate detection of voltage fluctuations.
• Adjustable reset threshold provides flexibility in different voltage level requirements.
• Manual reset input allows for external control and system debugging.

Disadvantages

• Limited number of available reset threshold options.
• SOT-23 package may not be suitable for all applications requiring higher pin counts.

Working Principles

ADM809JAKSZ-REEL operates by comparing the monitored voltage with the set threshold voltage. When the monitored voltage falls 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.
