Detailed Pin Configuration

The CAT810LSDI-T3 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 supply voltage and generates a reset signal when it falls below the threshold voltage.
• Provides a stable reset output during power-up and power-down sequences.
• Offers a fixed reset timeout period to ensure proper system initialization.

Advantages and Disadvantages
