---

| | --| VDD | --| /RESET| --| GND | |_______| ```

Pin Description: - VDD: Power supply input pin - /RESET: Active-low reset output pin - GND: Ground reference pin

Functional Features

• Voltage Monitoring: APX809-26SAG-7 continuously monitors the input voltage and asserts the reset signal when the voltage drops below the threshold.
• Reset Output: The active-low reset output (/RESET) remains asserted until the input voltage rises above the threshold and the reset timeout period elapses.
• Precision: The product offers high accuracy in voltage monitoring, ensuring reliable reset functionality.

Advantages and Disadvantages

Advantages

• Low power consumption makes it suitable for battery-powered applications.
• Wide operating voltage range allows for versatile use in various electronic circuits.
• Small package size enables space-saving designs.

Disadvantages

• Limited reset timeout period may not be suitable for applications requiring longer reset delays.
• Lack of adjustable threshold voltage limits customization options.

Working Principles

APX809-26SAG-7 operates based on a voltage comparator circuit. It compares the input voltage with the preset threshold voltage. When the input voltage drops below the threshold, the reset output is asserted. The reset signal remains active until the input voltage rises above the threshold and the reset timeout period elapses.
