Detailed Pin Configuration

CAT809RTBI-GT3 has three pins:

1. VDD: Power supply input pin.
2. GND: Ground reference pin.
3. RESET: Output pin that provides a reset signal when the monitored voltage falls below the threshold.

Functional Features

• Monitors the voltage level continuously.
• Generates a reset signal when the voltage drops below the specified threshold.
• Provides a stable output even during voltage fluctuations.
• Low quiescent current ensures minimal power consumption.

Advantages and Disadvantages

Advantages

• Wide operating voltage range allows compatibility with various systems.
• Small package size enables space-saving designs.
• High accuracy ensures reliable voltage monitoring.
• Low power consumption prolongs battery life in portable devices.

Disadvantages

• Limited reset threshold and timeout period options may not suit all applications.
• Lack of additional features such as hysteresis or adjustable thresholds.

Working Principles

CAT809RTBI-GT3 operates based on a voltage comparator circuit. It compares the input voltage with the preset threshold voltage. When the input voltage falls below the threshold, the reset signal is activated. The reset signal remains active until the voltage rises above the threshold or the timeout period elapses.
