Characteristics

• Voltage monitoring: The MCP120-270DI/TO is designed to monitor the supply voltage of a system and provide a reset signal when the voltage drops below a certain threshold.
• Reset function: It ensures that the system is properly initialized after a power-on or brown-out event.
• Low power consumption: The MCP120-270DI/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 6.0V.
• Small package size: The MCP120-270DI/TO is available in a small TO-92 package, which makes it easy to integrate into various electronic designs.

Packaging/Quantity

The MCP120-270DI/TO is typically packaged in reels or tubes, containing a specific quantity of units per package. The exact packaging and quantity may vary depending on the supplier.

Specifications

• Supply Voltage Range: 1.6V to 6.0V
• Reset Threshold Voltage: 2.63V
• Reset Timeout Period: 140ms (typical)
• Operating Temperature Range: -40°C to +85°C
• Package Type: TO-92

Detailed Pin Configuration

The MCP120-270DI/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 outputs a reset signal when the supply voltage drops below the threshold voltage.

Functional Features

• Under-Voltage Monitoring: The MCP120-270DI/TO continuously monitors the supply voltage and generates a reset signal when it falls below the threshold voltage.
• Reset Signal Output: The RESET pin provides an active-low reset signal to the system, indicating that the supply voltage is below the threshold.
• Power-On Reset: It ensures that the system is properly initialized after power-on, preventing any undefined behavior.
• Brown-Out Detection: The MCP120-270DI/TO can detect brown-out conditions, where the supply voltage drops temporarily, and generate a reset signal accordingly.

Advantages and Disadvantages

Advantages

• Reliable voltage monitoring and reset functionality.
• Low power consumption, suitable for battery-powered applications.
• Wide operating voltage range allows compatibility with various systems.
• Small package size enables easy integration into compact designs.

Disadvantages

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

Working Principles

The MCP120-270DI/TO utilizes an internal voltage reference and comparator to monitor the supply voltage. When the voltage drops below the preset threshold, the comparator triggers the reset circuitry, generating a reset signal. This signal remains active until the supply voltage rises above the threshold again.

Detailed Application Field Plans

The MCP120-270DI/TO finds applications in various electronic devices and systems, including but not limited to: - Microcontrollers and microprocessors - Embedded systems - Power management circuits - Industrial control systems - Automotive electronics - Consumer electronics
