MCP130-450FI/TO

Product Overview

Category

The MCP130-450FI/TO belongs to the category of integrated circuits (ICs).

Use

This product is commonly used in electronic devices for voltage monitoring and reset functions.

Characteristics

• Voltage monitoring: The MCP130-450FI/TO is designed to monitor the supply voltage of a system and provide a reset signal when the voltage falls below a certain threshold.
• Reset function: It ensures that the system is properly initialized after power-up or when the voltage drops below the specified level.
• Low power consumption: The MCP130-450FI/TO operates with low 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 MCP130-450FI/TO is available in a compact TO-92 package, which makes it suitable for space-constrained applications.

Package and Quantity

The MCP130-450FI/TO is packaged in a TO-92 package. It is typically sold in reels or tubes containing a specific quantity, such as 1000 units per reel.

Specifications

• Supply Voltage Range: 1.6V to 5.5V
• Threshold Voltage: 4.50V (typical)
• Reset Timeout Period: 140ms (typical)
• Operating Temperature Range: -40°C to +85°C

Pin Configuration

The MCP130-450FI/TO has three pins:

1. VDD: This pin is connected to the positive supply voltage.
2. GND: This pin is connected to the ground or negative supply voltage.
3. RESET: This pin provides the reset signal to the system when the voltage falls below the threshold.

Functional Features

• Voltage Monitoring: The MCP130-450FI/TO continuously monitors the supply voltage and compares it to the threshold voltage.
• Reset Signal Generation: When the supply voltage drops below the threshold, the MCP130-450FI/TO generates a reset signal to ensure proper system initialization.
• Reset Timeout: The reset signal remains active for a specific period (reset timeout) after the voltage rises above the threshold. This prevents false resets due to temporary voltage fluctuations.

Advantages and Disadvantages

Advantages

• Reliable Voltage Monitoring: The MCP130-450FI/TO provides accurate and reliable voltage monitoring, ensuring system stability.
• Low Power Consumption: It operates with low power consumption, making it suitable for battery-powered applications.
• Compact Size: The TO-92 package allows for easy integration into space-constrained designs.

Disadvantages

• Limited Threshold Voltage Options: The MCP130-450FI/TO has a fixed threshold voltage of 4.50V, which may not be suitable for all applications requiring different voltage levels.
• Single Reset Timeout Period: The reset timeout period is fixed at 140ms, which may not be optimal for all systems.

Working Principles

The MCP130-450FI/TO utilizes an internal voltage reference and comparator to monitor the supply voltage. When the voltage falls below the threshold, the comparator triggers the generation of a reset signal. The reset signal remains active for the specified reset timeout period, allowing the system to properly initialize. Once the voltage rises above the threshold, the reset signal deactivates.

Application Field Plans

The MCP130-450FI/TO finds applications in various electronic devices where voltage monitoring and reset functions are critical. Some potential application fields include:

1. Microcontrollers: Ensuring proper initialization and stable operation of microcontroller-based systems.
2. Embedded Systems: Providing reliable voltage monitoring and reset functionality in embedded systems.
3. Industrial Control Systems: Ensuring system stability and preventing data corruption in industrial control applications.
4. Automotive Electronics: Monitoring supply voltage in automotive electronic systems to prevent malfunctions.

Alternative Models

• MCP130-300FI/TO: Similar to MCP130-450FI/TO but with a threshold voltage of 3.00V.
• MCP130-500FI/TO: Similar to MCP130-450FI/TO but with a threshold voltage of 5.00V.
• MCP130T-270I/TT: A surface-mount alternative with a threshold voltage of 2.70V.

These alternative models provide different threshold voltage options, allowing for greater flexibility in voltage monitoring applications.
