Detailed Pin Configuration

ADM823TYKSZ-R7 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

• Monitors the voltage level and generates a reset signal when it falls below the set threshold.
• Provides a stable reset signal during power-up and power-down sequences.
• Offers an adjustable reset threshold voltage to suit different system requirements.
• Incorporates a built-in delay to prevent false resets caused by short voltage transients.

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.
• High accuracy ensures reliable voltage monitoring.
• Adjustable reset threshold voltage provides flexibility.

Disadvantages

• Limited reset timeout period may not be suitable for certain applications requiring longer timeouts.
• SOT-23-3 package may pose challenges for manual soldering.

Working Principles

ADM823TYKSZ-R7 operates by comparing the monitored voltage with the set threshold voltage. When the voltage falls below the threshold, the RESET pin is asserted, indicating a reset condition. The reset signal remains active until the voltage rises above the threshold and the reset timeout period elapses.
