Detailed Pin Configuration

The APX803L05-41SA-7 has three pins:

1. VDD: This pin is connected to the power supply voltage.
2. GND: This pin is connected to the ground.
3. RESET: This pin outputs a low signal when the monitored voltage drops below the threshold.

Functional Features

• Voltage Monitoring: The APX803L05-41SA-7 continuously monitors the input voltage and provides a reset signal when it falls below the specified threshold.
• Adjustable Delay Time: The reset output can be configured with an adjustable delay time to ensure stability during power-up or power-down sequences.
• Low Power Consumption: With a quiescent current of only 1.0µA, this voltage supervisor minimizes power consumption in battery-powered applications.

Advantages and Disadvantages

Advantages

• Wide operating voltage range allows for versatile use in different electronic systems.
• Adjustable delay time provides flexibility in timing requirements.
• Low-power consumption prolongs battery life in portable devices.

Disadvantages

• Limited threshold voltage options may not suit all voltage monitoring needs.
• SOT-23-3 package may be challenging to solder for inexperienced users.

Working Principles

The APX803L05-41SA-7 operates by comparing the input voltage with the preset threshold voltage. When the input voltage drops below the threshold, the reset output is activated, indicating a power failure or an abnormal condition. The adjustable delay time ensures that the reset signal remains stable during power transitions.

Detailed Application Field Plans

The APX803L05-41SA-7 finds applications in various fields, including:

1. Battery-Powered Devices: It ensures proper shutdown or system reset when the battery voltage drops below a critical level.
2. Industrial Control Systems: It provides voltage monitoring and reset functions in control panels and automation equipment.
3. Automotive Electronics: It safeguards sensitive components from voltage fluctuations and ensures reliable operation.
