Detailed Pin Configuration

APX809-44SRG-7 has three pins:

1. VDD: Power supply input pin.
2. GND: Ground reference pin.
3. RESET: Output pin that indicates the status of the monitored voltage.

Functional Features

• Voltage Monitoring: APX809-44SRG-7 continuously monitors the voltage level at the VDD pin.
• Reset Function: When the voltage drops below the reset threshold, the RESET pin is asserted, indicating a reset condition.
• Reset Timeout: The reset condition is maintained for a specific timeout period, after which the RESET pin is de-asserted.

Advantages and Disadvantages

Advantages

• Low power consumption ensures minimal impact on overall system performance.
• Wide operating voltage range allows compatibility with various electronic systems.
• High accuracy ensures reliable voltage monitoring and reset functionality.
• Small package size enables space-saving integration into compact designs.

Disadvantages

• Limited reset timeout period may not be suitable for certain applications requiring longer reset durations.
• Lack of adjustable reset threshold voltage limits customization options for specific voltage level requirements.

Working Principles

APX809-44SRG-7 operates based on a voltage comparator circuit. It compares the voltage at the VDD pin with the preset threshold voltage. When the voltage drops below the threshold, the comparator triggers the reset function, asserting the RESET pin. The reset condition is maintained for the specified timeout period before de-asserting the RESET pin.
