Essence

The essence of this product lies in its ability to provide accurate voltage monitoring and reset functions, ensuring the stable operation of electronic devices.

Packaging/Quantity

The APX803L05-42SA-7 is typically packaged in reels, with 3000 units per reel.

Specifications

• Supply Voltage Range: 1.8V to 5.5V
• Threshold Voltage: 4.2V ± 1.5%
• Reset Output Delay Time: Adjustable from 1ms to 10s
• Operating Temperature Range: -40°C to +85°C

Detailed Pin Configuration

The APX803L05-42SA-7 has five pins:

1. VDD: Power supply input
2. GND: Ground reference
3. MR: Manual reset input (active-low)
4. RESET: Reset output
5. NC: No connection (unused pin)

Functional Features

• Voltage monitoring: The APX803L05-42SA-7 continuously monitors the supply voltage and provides a reset signal when it falls below the threshold voltage.
• Manual reset: The manual reset input allows for an external reset signal to override the internal monitoring function.
• Adjustable reset delay: The reset output delay time can be adjusted according to the specific requirements of the application.

Advantages and Disadvantages

Advantages

• Low power consumption ensures minimal impact on overall system performance.
• Wide operating voltage range allows for compatibility with various electronic devices.
• High accuracy in voltage monitoring ensures reliable operation.
• Small package size enables space-saving designs.

Disadvantages

• The adjustable reset delay time may require additional configuration and testing efforts during the design phase.

Working Principles

The APX803L05-42SA-7 operates by comparing the supply voltage with the threshold voltage. When the supply voltage drops below the threshold, the reset output is activated, indicating a low-voltage condition. The reset output remains active until the supply voltage rises above the threshold and the reset delay time elapses.

Detailed Application Field Plans

The APX803L05-42SA-7 finds applications in various fields, including:

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