Detailed Pin Configuration

APX803-23SRG-7 has three pins:

1. VDD: Connect this pin to the power supply voltage.
2. GND: Connect this pin to the ground.
3. RESET: This pin provides the reset output signal.

Functional Features

• Monitors the power supply voltage and generates a reset signal when it falls below the threshold voltage.
• The delay time can be adjusted to allow for proper stabilization of the power supply before releasing the reset signal.
• Provides an active-low reset output signal.

Advantages and Disadvantages

Advantages

• Low-power consumption makes it suitable for battery-powered devices.
• Wide operating voltage range allows for compatibility with various power supply systems.
• High accuracy ensures reliable voltage monitoring.
• Adjustable delay time provides flexibility in different applications.

Disadvantages

• Limited threshold voltage options may not cover all voltage requirements.
• The SOT-23-3 package may not be suitable for applications with space constraints.

Working Principles

APX803-23SRG-7 works by comparing the power supply voltage with the threshold voltage. If the power supply voltage drops below the threshold, the reset output is activated. The delay time can be adjusted to allow for proper stabilization of the power supply before releasing the reset signal.
