Detailed Pin Configuration

The APX803L20-30SA-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

• Accurate voltage monitoring: The APX803L20-30SA-7 ensures precise monitoring of the supply voltage.
• Reset function: It generates a reset signal when the voltage drops below the specified threshold.
• Power-on reset delay: The device includes a power-on reset delay to prevent false resets during power-up.

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.

Disadvantages

• The reset timeout period may not be adjustable, limiting its flexibility in certain applications.
• Lack of additional features such as adjustable voltage thresholds or hysteresis.

Working Principles

The APX803L20-30SA-7 operates by continuously monitoring the supply voltage. When the voltage drops below the specified threshold, the device generates a reset signal. This signal remains active until the voltage rises above the threshold and the reset timeout period elapses.
