• Low power consumption: This IC is designed to operate with minimal power consumption, making it suitable for battery-powered applications.
• Wide operating voltage range: It can operate within a wide voltage range, typically from 1.6V to 5.5V.
• Small package size: The MCP130-475FI/TO is available in a compact TO-92 package, which makes it easy to integrate into various circuit designs.
• High accuracy: It provides precise voltage monitoring, ensuring reliable system operation.

Package and Quantity

The MCP130-475FI/TO is packaged in a TO-92 package. Each package contains one unit of the IC.

Specifications

• Supply Voltage Range: 1.6V to 5.5V
• Reset Threshold Voltage: 4.75V
• Reset Timeout Period: 140ms (typical)
• Operating Temperature Range: -40°C to +85°C
• Quiescent Current: 10µA (typical)

Pin Configuration

The MCP130-475FI/TO has three pins:

1. VDD: Connect this pin to the positive supply voltage.
2. GND: Connect this pin to the ground or negative supply voltage.
3. RESET: This pin outputs the reset signal when the supply voltage falls below the threshold.

Functional Features

• Voltage Monitoring: The MCP130-475FI/TO continuously monitors the supply voltage and compares it to the preset threshold voltage.
• Reset Generation: When the supply voltage drops below the threshold, the IC generates a reset signal to initiate system reset or recovery.
• Reset Timeout: The MCP130-475FI/TO includes a timeout feature that ensures the reset signal is not held indefinitely. After a specified period, the reset signal is released.

Advantages and Disadvantages

Advantages

• Precise voltage monitoring ensures reliable system operation.
• Low power consumption makes it suitable for battery-powered applications.
• Wide operating voltage range allows compatibility with various systems.
• Compact package size facilitates integration into different circuit designs.

Disadvantages

• Limited reset timeout options may not be suitable for all applications.
• Lack of adjustable threshold voltage limits customization possibilities.

Working Principles

The MCP130-475FI/TO operates by comparing the supply voltage with the preset threshold voltage. When the supply voltage falls below the threshold, the IC triggers the reset signal. This signal remains active until the supply voltage rises above the threshold or the timeout period elapses.

Application Field Plans

The MCP130-475FI/TO finds applications in various electronic devices where voltage monitoring and reset generation are critical. Some potential application fields include:

1. Microcontrollers: Ensuring proper system initialization and recovery after power disruptions.
2. Embedded Systems: Providing reliable reset functionality for stable operation.
3. Industrial Control Systems: Monitoring power supply integrity and initiating system resets when necessary.
4. Automotive Electronics: Safeguarding critical components by resetting them during voltage fluctuations.
5. Consumer Electronics: Enhancing system reliability by preventing erratic behavior due to power supply issues.

Alternative Models
