Essence

The essence of the MCP130T-315I/SN lies in its ability to ensure stable power supply voltage by monitoring and controlling it within specified limits.

Packaging/Quantity

The MCP130T-315I/SN is typically packaged in reels or tubes, with a quantity of 2500 units per reel/tube.

Specifications

• Supply Voltage Range: 1.6V to 6.0V
• Threshold Voltage Options: 2.93V
• Reset Timeout Period: 140ms (typical)
• Quiescent Current: 1.0µA (typical)
• Operating Temperature Range: -40°C to +125°C

Detailed Pin Configuration

The MCP130T-315I/SN has the following pin configuration:

1. VDD: Power supply input
2. GND: Ground reference
3. RESET: Active-low reset output
4. N/C: No connection (unused pin)

Functional Features

• Voltage Monitoring: The MCP130T-315I/SN continuously monitors the power supply voltage and provides a reset signal when it falls below the threshold voltage.
• Reset Output: The device generates an active-low reset signal to indicate that the power supply voltage is below the threshold.
• Reset Timeout: If the power supply voltage remains below the threshold for a specified period, the MCP130T-315I/SN asserts the reset output for the reset timeout duration.

Advantages and Disadvantages

Advantages

• High precision and accuracy in voltage monitoring
• Low quiescent current consumption
• Wide operating temperature range
• Small form factor for easy integration

Disadvantages

• Limited threshold voltage options
• No adjustable timeout period

Working Principles

The MCP130T-315I/SN operates by comparing the power supply voltage with the preset threshold voltage. When the voltage drops below the threshold, the device triggers the reset output. If the voltage remains below the threshold for the specified reset timeout period, the reset output is asserted.

Detailed Application Field Plans

The MCP130T-315I/SN finds applications in various electronic systems where stable power supply voltage monitoring is critical. Some of the potential application fields include:

1. Microcontrollers and Microprocessors: Ensuring reliable operation by monitoring the power supply voltage.
2. Industrial Control Systems: Preventing malfunctions due to voltage fluctuations.
3. Automotive Electronics: Protecting sensitive components from voltage variations.
4. Battery-Powered Devices: Monitoring battery voltage to prevent over-discharge.

Detailed and Complete Alternative Models

1. MCP1316T-29LE/OT: Similar to MCP130T-315I/SN but with a different threshold voltage option (2.9V).
2. MAX809T: Voltage supervisor with adjustable reset timeout period.
3. TPS3839K33DBVR: Ultra-low-power voltage supervisor with a fixed threshold voltage of 3.3V.

These alternative models offer similar functionality and can be considered based on specific requirements.
