```

---

| | --| VCC GND |-- Pin 1: Ground (GND) --| RESET OUT |-- Pin 2: Reset Output --| MR |-- Pin 3: Manual Reset Input --| VTH |-- Pin 4: Voltage Threshold Adjust --| GND VCC |-- Pin 5: Supply Voltage (VCC) --| RESET IN |-- Pin 6: Reset Input --| RESET |-- Pin 7: Reset Output |___________| ```

Functional Features

1. Voltage Monitoring: ADM692ANZ continuously monitors the supply voltage.
2. Reset Signal Generation: When the supply voltage drops below the specified threshold, the IC generates a reset signal.
3. Manual Reset: The IC includes a manual reset input (MR) for initiating a reset externally.
4. Adjustable Threshold: The voltage threshold for generating the reset signal can be adjusted using the VTH pin.
5. Power-On Reset Delay: ADM692ANZ provides a power-on reset delay to ensure stable operation during power-up.

Advantages and Disadvantages

Advantages

• Reliable voltage monitoring and reset functionality.
• Low power consumption.
• Wide operating voltage range.
• Adjustable threshold and timeout period.
• Compact SOIC package.

Disadvantages

• Limited pin count may restrict the number of additional features that can be integrated.
• Not suitable for applications requiring complex reset timing sequences.

Working Principles

ADM692ANZ operates by continuously monitoring the supply voltage. When the voltage drops below the specified threshold, the IC generates a reset signal. This signal remains active until the voltage rises above the threshold or a manual reset is initiated. The adjustable threshold allows customization according to specific application requirements.
