MCP130-485HI/TO

Supervisors Overview

The MCP130-485HI/TO is a supervisory circuit manufactured by Microchip Technology, designed to monitor system voltage levels. It features an open-drain output with an integrated 5k pull-up resistor and operates in the TO-92 package. The device maintains the microcontroller in reset until the supply voltage reaches a stable operating level, ensuring reliable startup. It supports a maximum supply voltage of 5.5 V and functions within an industrial temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Maintains microcontroller in reset until supply voltage reaches stable operating level
• Integrates 5k pull-up resistor for active-low output signaling
• Resets microcontroller during power loss events

Supervisors Applications

• Microcontroller system supervision
• Power loss detection circuits
• Voltage monitoring in embedded systems

Supervisors Procurement Notes

Verify the specific suffix HI against official Microchip documentation to confirm pinout and electrical characteristics. Ensure the TO-92 package matches your PCB footprint requirements. Cross-reference the part number with authorized distributors to avoid counterfeit components. Confirm that the 5.5V maximum rating aligns with your system's voltage rails before procurement.

Supervisors Selection Notes

Select this component when a low-cost, single-supervisor solution is required for basic voltage monitoring. The integrated pull-up simplifies interface design by reducing external component count. Consider the TO-92 package constraints if space is limited. Verify that the fixed threshold voltage meets the specific reset requirement of the target microcontroller.

Supervisors Part Context

This part belongs to the MCP130 series of supervisory circuits from Microchip Technology. The series is designed for cost-sensitive applications requiring basic voltage monitoring. The MCP130 family typically offers various threshold voltages and package options to suit different system needs while maintaining consistent functional behavior across the lineup.

Supervisors Replacement Considerations

Check for direct substitutes within the MCP130 series with compatible threshold voltages. Verify pin compatibility for TO-92 packages. Ensure replacement parts maintain the same 5.5V maximum supply voltage and operating temperature range.
