2. GND: Connects to the ground or negative supply voltage.
3. RESET: Output pin that provides a reset signal when the monitored voltage falls below the threshold.

Functional Features

• Voltage Monitoring: The APX803L05-29W-7 continuously monitors the input voltage and provides a reset signal when it drops below the specified threshold.
• Reset Signal Generation: When the monitored voltage falls below the threshold, the device generates a reset signal to ensure proper system operation.
• Power-On Reset: The APX803L05-29W-7 also generates a reset signal during power-up to ensure a controlled start-up sequence.

Advantages and Disadvantages

Advantages

• Low-power consumption makes it suitable for battery-powered applications.
• Wide operating voltage range allows compatibility with various systems.
• Small package size enables space-saving designs.
• High accuracy ensures reliable voltage monitoring.

Disadvantages

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

Working Principles

The APX803L05-29W-7 operates by comparing the input voltage with the preset threshold voltage. When the input voltage drops below the threshold, the device triggers a reset signal. This signal remains active until the input voltage rises above the threshold again.
