1. VDD: Connects to the positive supply voltage.
2. GND: Connects to the ground or negative supply voltage.
3. MR: Manual reset input pin, used to manually reset the device.

Functional Features

The MCP120-475DI/TO offers the following functional features:

• Voltage monitoring: It continuously monitors the supply voltage and provides a reset signal when it falls below the specified threshold.
• Manual reset input: The manual reset input allows for external control over the reset function, enabling system initialization or recovery.
• Open-drain output: The reset output is an open-drain configuration, allowing for easy interfacing with other devices.

Advantages and Disadvantages

Advantages: - Wide supply voltage range allows for compatibility with various systems. - Low quiescent current minimizes power consumption. - Accurate reset threshold ensures reliable operation.

Disadvantages: - Limited reset threshold options may not suit all applications. - Manual reset input requires external control, which may add complexity to the system design.

Working Principles

The MCP120-475DI/TO operates by comparing the supply voltage with a preset threshold. When the voltage falls below the threshold, the device triggers a reset signal. The manual reset input allows for additional control over the reset function.
