Pin Configuration

ADM809JAKSZ-REEL7 has three pins:

1. VCC: Power supply input
2. GND: Ground connection
3. RESET: Output signal indicating system reset status

Functional Features

• Monitors the supply voltage and generates a reset signal when it falls below the specified threshold.
• Provides a stable reset output during power-up and power-down conditions.
• Offers a manual reset input for immediate system reset.
• Includes a built-in glitch immunity circuit to prevent false resets.

Advantages and Disadvantages

Advantages

• Low power consumption makes it suitable for battery-powered applications.
• Wide operating voltage range allows compatibility with various systems.
• High accuracy ensures reliable voltage monitoring.
• Small package size enables space-saving designs.

Disadvantages

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

Working Principles

ADM809JAKSZ-REEL7 operates by comparing the supply voltage with a fixed threshold voltage. When the supply voltage drops below the threshold, the reset output is activated, indicating a system reset. The reset signal remains active until the supply voltage rises above the threshold and the reset timeout period elapses.
