```

---

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

• VCC: Power supply input
• GND: Ground reference
• RESET: Output reset signal

Functional Features

• Voltage monitoring: ADM825ZYKSZ-R7 continuously monitors the supply voltage.
• Reset signal generation: When the supply voltage falls below the set threshold, the device generates a reset signal.
• Adjustable timeout period: The reset signal remains active for a programmable timeout period after the voltage returns to normal.
• Power-on reset: The device generates a reset signal upon power-up to ensure proper initialization of the system.

Advantages and Disadvantages

Advantages

• Reliable voltage monitoring and reset signal generation.
• Low power consumption.
• Compact package size for easy integration.
• Wide operating temperature range for versatile applications.
• Adjustable reset timeout period for flexibility.

Disadvantages

• Limited number of available reset threshold voltage options.
• Limited number of available reset timeout period options.

Working Principles

ADM825ZYKSZ-R7 operates by comparing the supply voltage with the set threshold voltage. If the supply voltage drops below the threshold, the device generates a reset signal. The reset signal remains active for the programmed timeout period, allowing the system to properly recover before resuming normal operation.
