```

---

| | --| RESET |-- --| GND |-- --| VCC |-- |_______| ```

Pin Descriptions: - RESET: Output pin that provides a reset signal when the monitored voltage falls below the threshold. - GND: Ground reference pin. - VCC: Power supply input pin.

Functional Features

1. Voltage Monitoring: ADM823YYKS-R7 continuously monitors the supply voltage.
2. Reset Signal Generation: When the monitored voltage falls below the threshold, the IC generates a reset signal on the RESET pin.
3. Adjustable Timeout Period: The reset timeout period can be adjusted using external capacitors, allowing flexibility in system design.
4. Power-On Reset: ADM823YYKS-R7 provides a power-on reset signal to ensure proper initialization of the system during power-up.

Advantages and Disadvantages

Advantages

• Wide operating voltage range allows compatibility with various systems.
• Low power consumption makes it suitable for battery-powered applications.
• Small package size enables usage in space-constrained designs.
• Adjustable reset timeout period provides flexibility in system design.

Disadvantages

• Lack of built-in hysteresis may lead to potential noise-related issues.
• Limited number of available alternative models in the market.

Working Principles

ADM823YYKS-R7 operates by comparing the supply voltage with a preset threshold. When the voltage drops below the threshold, the IC triggers a reset signal. This signal remains active until the voltage rises above the threshold or the adjustable timeout period elapses.
