Essence

This product serves as a voltage supervisor and reset generator in electronic systems.

Packaging/Quantity

The CAT809SSDI-T3 is typically packaged in reels containing 3000 units.

Specifications

• Supply Voltage Range: 1.0V to 5.5V
• Reset Threshold Voltage Options: 2.63V, 2.93V, 3.08V, 4.38V
• Reset Timeout Period: 140ms (min)
• Operating Temperature Range: -40°C to +125°C

Detailed Pin Configuration

The CAT809SSDI-T3 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 supply voltage and generates a reset signal when it drops below the specified threshold.
• Provides a stable reset output during power-up and power-down sequences.
• Offers a fixed reset timeout period to ensure proper system initialization.

Advantages

• Low power consumption helps conserve energy in 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.

Disadvantages

• Limited reset threshold voltage options may not suit all applications.
• Fixed reset timeout period may not be adjustable for specific system requirements.

Working Principles

The CAT809SSDI-T3 utilizes a voltage comparator to monitor the supply voltage. When the voltage drops below the specified threshold, the reset output is activated. The reset signal remains active until the voltage rises above the threshold or power is removed.
