2. GND: Ground reference pin.
3. RESET: Active-low reset output pin.

Functional Features

• Accurate voltage monitoring: The APX803L20-13SA-7 provides precise detection of voltage levels within the specified range.
• Active-low reset output: The device generates an active-low reset signal when the monitored voltage falls below the threshold level.
• Built-in delay time: The integrated delay time ensures that the reset signal remains stable for a specific duration after the voltage returns to the normal range.

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.
• Accurate voltage monitoring ensures reliable system operation.

Disadvantages

• The fixed threshold voltage may not be suitable for all applications requiring different voltage levels.
• Lack of adjustable delay time limits customization options.

Working Principles

The APX803L20-13SA-7 operates by comparing the input voltage with the internally set threshold voltage. When the input voltage drops below the threshold, the reset output is activated, indicating a low-voltage condition. The built-in delay time ensures that the reset signal remains active for a specific duration after the voltage returns to the normal range, preventing false triggering due to temporary voltage fluctuations.

Detailed Application Field Plans

The APX803L20-13SA-7 finds application in various fields, including:

1. Battery-powered devices: It can be used to monitor battery voltage and trigger actions when the voltage falls below a certain level.
2. Power supply units: The voltage detector ensures stable operation by providing a reset signal in case of voltage abnormalities.
3. Industrial control systems: It can be employed to monitor critical voltages in industrial equipment and initiate appropriate actions in case of voltage deviations.
