Essence

The essence of APX803L-14SA-7 lies in its ability to accurately monitor voltage levels and provide a reliable output signal.

Packaging/Quantity

The product is typically packaged in reels, with each reel containing a specified quantity of APX803L-14SA-7 units.

Specifications

• Operating Voltage Range: 1.2V to 6.0V
• Detection Voltage Accuracy: ±1.5%
• Quiescent Current: 1.0μA (typical)
• Output Type: Active low
• Operating Temperature Range: -40°C to +85°C

Detailed Pin Configuration

The APX803L-14SA-7 has three pins:

1. VDD: Connect this pin to the positive supply voltage.
2. GND: Connect this pin to the ground.
3. RESET: This pin outputs a low signal when the detected voltage falls below the threshold.

Functional Features

• Voltage Monitoring: The APX803L-14SA-7 continuously monitors the input voltage and provides an output signal when it falls below the detection threshold.
• Hysteresis Function: The built-in hysteresis ensures stable output even in noisy environments.
• Low Power Consumption: With a quiescent current of only 1.0μA, the device minimizes power consumption.

Advantages and Disadvantages

Advantages

• High accuracy voltage detection
• Low power consumption
• Wide operating voltage range
• Small package size for space-constrained applications

Disadvantages

• Limited number of pins for additional functionality
• Lack of adjustable detection threshold

Working Principles

The APX803L-14SA-7 operates by comparing the input voltage with a fixed detection threshold. When the voltage falls below this threshold, the RESET pin outputs a low signal. The hysteresis function ensures that the output remains stable even in the presence of noise or voltage fluctuations.

Detailed Application Field Plans

The APX803L-14SA-7 finds applications in various fields, including:

1. Battery-Powered Devices: It can be used to monitor battery voltage levels and trigger actions when they reach critical levels.
2. Power Management Systems: The device can be integrated into power management circuits to detect undervoltage conditions and initiate appropriate actions.
3. Industrial Control Systems: It is suitable for monitoring voltage levels in industrial control systems to ensure proper functioning and prevent damage.

Detailed and Complete Alternative Models

Some alternative models to APX803L-14SA-7 include:

1. APX803L-31SA-7: Similar to APX803L-14SA-7 but with a higher detection voltage threshold.
2. APX803M-14SA-7: A variant with an active-high output instead of active-low.
3. APX804L-14SA-7: Offers adjustable detection threshold for more flexibility.
