Packaging/Quantity

The APX803L05-13SA-7 is typically packaged in reels or tubes, with a quantity of 3000 units per reel/tube.

Specifications

• Supply Voltage Range: 1.2V to 5.5V
• Threshold Voltage: 4.63V ± 2.5%
• Reset Timeout Period: 140ms (typical)
• Quiescent Current: 1.0µA (typical)
• Operating Temperature Range: -40°C to +85°C

Detailed Pin Configuration

The APX803L05-13SA-7 has three pins:

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

Functional Features

• Voltage Monitoring: The APX803L05-13SA-7 continuously monitors the input voltage and compares it to the threshold voltage.
• Reset Output: When the input voltage drops below the threshold, the RESET pin goes low, indicating a reset condition.
• Reset Timeout: The reset signal remains active for a fixed period (140ms) after the voltage rises above the threshold.

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.
• Accurate voltage monitoring ensures reliable system operation.

Disadvantages

• The reset timeout period may not be adjustable, limiting flexibility in certain applications.
• Limited availability of alternative models with different specifications.

Working Principles

The APX803L05-13SA-7 operates by comparing the input voltage with the internally set threshold voltage. When the input voltage falls below the threshold, the reset output is activated. The reset signal remains active for a fixed period, ensuring that the system is properly reset before normal operation resumes.
