Detailed Pin Configuration

The MCP130T-450I/TT has three pins:

1. VDD: This pin is connected to the power supply voltage.
2. GND: This pin is connected to the ground.
3. RESET: This pin outputs a reset signal when the voltage falls below the threshold.

Functional Features

• Monitors power supply voltage and provides a reset signal when the voltage falls below the threshold.
• Low quiescent current consumption, making it suitable for battery-powered applications.
• Wide supply voltage range allows compatibility with various systems.
• Accurate voltage threshold ensures reliable operation.

Advantages and Disadvantages

Advantages

• Small package size enables use in space-constrained designs.
• Low quiescent current prolongs battery life.
• Accurate voltage threshold ensures precise monitoring.

Disadvantages

• Limited to a specific voltage threshold of 4.50V.
• Not suitable for applications requiring a different voltage threshold.

Working Principles

The MCP130T-450I/TT works by comparing the power supply voltage with a fixed threshold of 4.50V. When the voltage falls below this threshold, the RESET pin is activated, providing a reset signal to the system. This helps prevent erratic behavior or data corruption caused by insufficient voltage.
