Essence

The essence of APX803-44SRG-7 lies in its ability to provide accurate voltage monitoring and reset functionality in electronic devices.

Packaging/Quantity

This product is typically packaged in reels, with each reel containing a specific quantity of APX803-44SRG-7 units.

Specifications

• Operating Voltage Range: 1.0V to 5.5V
• Threshold Voltage: 4.4V
• Accuracy: ±1.5%
• Quiescent Current: 1.0µA (typical)
• Power-On Reset Time: 20ms (typical)

Detailed Pin Configuration

APX803-44SRG-7 has three pins:

1. VDD: Connects to the power supply voltage.
2. GND: Ground reference.
3. RESET: Output pin that provides a reset signal when the monitored voltage falls below the threshold.

Functional Features

• Monitors the power supply voltage continuously.
• Generates a reset signal when the voltage drops below the threshold.
• Provides a stable and reliable reset function for the connected system.

Advantages

• Low power consumption helps in energy-efficient designs.
• Wide operating voltage range makes it compatible with various systems.
• High accuracy ensures precise voltage monitoring.
• Small package size allows for space-saving integration into compact devices.
• Reset output signal enables controlled system reset during voltage fluctuations.

Disadvantages

• Limited threshold voltage options may not suit all applications.
• Lack of additional features like adjustable threshold voltage or hysteresis.

Working Principles

APX803-44SRG-7 operates by comparing the power supply voltage with a fixed threshold. When the voltage drops below the threshold, the reset output is activated, indicating a power failure or unstable voltage condition. This helps in preventing erratic behavior or data corruption in the connected system.

Detailed Application Field Plans

APX803-44SRG-7 finds applications in various electronic systems where reliable voltage monitoring and controlled system reset are crucial. Some potential application fields include:

1. Microcontrollers and microprocessors
2. Embedded systems
3. Power management circuits
4. Battery-powered devices
5. Industrial automation systems
