• Low power consumption: The MCP120-450HI/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 MCP120-450HI/TO is available in a small TO-92 package, which makes it suitable for space-constrained designs.
• RoHS compliant: This product meets the Restriction of Hazardous Substances directive, ensuring its environmental friendliness.

Package and Quantity

The MCP120-450HI/TO is packaged in a TO-92 package. It is typically sold in reels containing a specified quantity of units, such as 1000 pieces per reel.

Specifications

• Supply Voltage Range: 1.6V to 5.5V
• Threshold Voltage Accuracy: ±50mV
• Reset Timeout Period: 140ms (typical)
• Operating Temperature Range: -40°C to +85°C
• Package Type: TO-92

Detailed Pin Configuration

The MCP120-450HI/TO has three pins:

1. VDD: Power supply input pin.
2. GND: Ground reference pin.
3. RESET: Output pin that provides a reset signal to the microcontroller or other digital circuitry.

Functional Features

• Voltage monitoring: The MCP120-450HI/TO continuously monitors the supply voltage and compares it with a preset threshold.
• Reset signal generation: When the supply voltage falls below the threshold, the MCP120-450HI/TO generates a reset signal, ensuring a controlled restart of the system.
• Reset timeout: The product includes a built-in reset timeout period to prevent false resets due to temporary voltage fluctuations.

Advantages and Disadvantages

Advantages

• Reliable voltage monitoring and reset functionality.
• Low power consumption.
• Wide operating voltage range.
• Small package size for space-constrained designs.
• RoHS compliant, environmentally friendly.

Disadvantages

• Limited number of pins for additional functionalities.
• May require external components for specific applications.

Working Principles

The MCP120-450HI/TO operates by comparing the supply voltage with a preset threshold. When the voltage drops below this threshold, the internal circuitry triggers a reset signal. This ensures that the microcontroller or other digital circuitry starts in a known state after power-up or a voltage drop. The reset signal remains active until the supply voltage rises above the threshold and the reset timeout period elapses.

Detailed Application Field Plans

The MCP120-450HI/TO is widely used in various electronic devices and systems, including but not limited to: - Embedded systems - Microcontrollers - Industrial automation - Consumer electronics - Power management circuits - Battery-powered devices
