• Delay Time Options: 20ms or 140ms
• Operating Temperature Range: -40°C to +85°C

Detailed Pin Configuration

APX803L20-22SA-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 monitored voltage drops below the threshold.

Functional Features

• Monitors the supply voltage continuously.
• Generates a reset signal when the voltage falls below the specified threshold.
• Adjustable delay time allows customization based on application requirements.
• Low quiescent current ensures minimal power consumption.

Advantages and Disadvantages

Advantages

• Wide operating voltage range makes it suitable for various applications.
• High accuracy ensures reliable voltage monitoring.
• Small package size enables space-saving designs.
• Adjustable delay time provides flexibility.

Disadvantages

• Limited threshold voltage options may not cater to all voltage level requirements.
• Lack of additional features such as hysteresis or watchdog functionality.

Working Principles

APX803L20-22SA-7 operates by comparing the supply voltage with the preset threshold voltage. When the supply voltage drops below the threshold, the reset output is activated, indicating a power failure or abnormal voltage condition. The delay time allows for stable voltage recovery before releasing the reset signal.
