MCP810T-485I/TT

Supervisors Overview

The MCP810T-485I/TT is a single-channel voltage supervisor integrated circuit manufactured by Microchip Technology. It operates within a supply voltage range up to 5.5 V and features a fixed threshold voltage of 4.725 V for monitoring power rails. The device provides an active high, push-pull output signal to indicate reset conditions. It includes a minimum reset timeout period of 150 ms to ensure stable system initialization. The component is designed for surface mount installation in a compact SOT-23-3 package. It supports an operating temperature range from -40°C to +85°C, making it suitable for industrial applications requiring reliable power management supervision.

Supervisors Feature Summary

• Provides active high reset signal with push-pull output configuration
• Monitors a single voltage channel with fixed threshold detection
• Ensures system stability through defined reset timeout duration

Supervisors Applications

• Industrial control systems requiring power rail supervision
• Embedded devices needing reliable power-on reset sequences
• Consumer electronics utilizing standard voltage logic levels

Supervisors Procurement Notes

Verify the specific suffix TT indicates tape and reel packaging when ordering. Confirm the I designation matches the required industrial temperature grade for your application environment. Ensure the SOT-23-3 footprint aligns with your PCB layout constraints. Cross-reference the manufacturer part number against official Microchip documentation to confirm current production status and compliance with RoHS standards before finalizing procurement plans.

Supervisors Selection Notes

Select this component when a simple, low-pin-count solution for voltage monitoring is required. The fixed threshold eliminates the need for external resistors, simplifying design. Consider the push-pull output capability if driving loads directly without additional buffering. Evaluate the thermal performance within the specified operating range to ensure long-term reliability in enclosed or high-temperature environments.

Supervisors Part Context

This part belongs to the MCP810 series of supervisory circuits from Microchip Technology. The series focuses on providing essential power management functions in minimal footprints. Similar parts in the family may offer different thresholds, output types, or manual reset capabilities. The MCP810 variant specifically targets applications where a straightforward, cost-effective voltage monitor is sufficient for system protection.

Supervisors Replacement Considerations

Direct substitutes must match the SOT-23-3 package and active high push-pull output. Verify that alternative components support the same 4.725 V threshold or can be adjusted via external components if necessary. Ensure compatibility with the 150 ms reset timeout requirement to maintain system integrity during power transitions.
