MCP130-485FI/TO

Supervisors Overview

The MCP130-485FI/TO is a microcontroller supervisory circuit manufactured by Microchip Technology. It features an open drain output with an internal 5kΩ pull-up resistor. The device monitors supply voltage and asserts an active low reset signal when the input drops below the threshold of 4.75V. It operates within a supply voltage range of 1V to 5.5V. The reset timeout period is 350ms. The component supports AEC-Q100 qualification for automotive applications and functions across an extended industrial temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Provides precise voltage monitoring to maintain microcontroller reset until supply stabilizes
• Integrates an internal 5kΩ pull-up resistor with open drain output configuration
• Supports brown-out protection during power loss events

Supervisors Applications

• Microcontroller system supervision in embedded designs
• Automotive electronics requiring AEC-Q100 qualified components
• Industrial control systems operating in extended temperature environments

Supervisors Procurement Notes

Verify the specific suffix FI/TO against official Microchip documentation to confirm package type and temperature grade. Ensure the part number matches the required 4.75V threshold voltage. Confirm AEC-Q100 compliance requirements if deploying in automotive contexts. Cross-reference datasheet revisions to ensure compatibility with existing design specifications.

Supervisors Selection Notes

Select this component when a fixed 4.75V threshold is required for system supervision. The integrated pull-up resistor simplifies interface connections to microcontroller reset pins. Consider the 350ms timeout duration relative to system startup requirements. Verify that the SOIC-8 or TO-92 package options meet board layout constraints.

Supervisors Part Context

This part belongs to the MCP130 series of voltage supervisory circuits designed for microcontroller applications. The series offers various trip voltages and packaging options including TO-92, SOT23-3, and SOIC-8. These devices are engineered to prevent erratic behavior caused by unstable power supplies.

Supervisors Replacement Considerations

Other MCP130 variants with different threshold voltages may serve as substitutes if the voltage level differs. Verify pinout compatibility and package dimensions before substitution.
