```

---

| | --| VCC |-- --| /MR |-- --| GND |-- |_______| ```

Pin descriptions: - VCC: Power supply input pin (+) - /MR: Active-low manual reset input pin - GND: Ground pin (-)

Functional Features

1. Voltage Monitoring: ADM811TARTZ-REEL continuously monitors the supply voltage.
2. Reset Signal Generation: When the supply voltage drops below the specified threshold, it generates a reset signal.
3. Manual Reset: The active-low manual reset input (/MR) allows for an external reset signal.

Advantages and Disadvantages

Advantages

• Reliable voltage monitoring and reset functionality.
• Small package size suitable for space-constrained applications.
• Wide operating voltage range allows compatibility with various systems.

Disadvantages

• Limited reset timeout period options may not meet specific application requirements.
• Lack of additional features such as adjustable reset thresholds or programmable timeout periods.

Working Principles

ADM811TARTZ-REEL operates by comparing the supply voltage against the preset threshold voltage. If the supply voltage falls below the threshold, the reset output is activated. The reset remains active until the supply voltage rises above the threshold or a manual reset signal is applied.

Detailed Application Field Plans

ADM811TARTZ-REEL finds applications in various electronic devices where reliable voltage monitoring and reset functionality are essential. Some potential application fields include:

1. Microcontrollers: Ensuring proper initialization and operation after power-up.
2. Embedded Systems: Providing a reset signal to ensure stable system startup.
3. Industrial Control Systems: Monitoring power supply integrity and initiating system recovery if necessary.
4. Communication Equipment: Preventing data corruption during power fluctuations.
5. Consumer Electronics: Enhancing the reliability of devices like smart home appliances and wearable devices.
