MCP810T-270I/TT

Supervisors Overview

The MCP810T-270I/TT is a single-channel voltage supervisory circuit manufactured by Microchip Technology. It operates within a supply voltage range up to 5.5 V and features a fixed threshold voltage of 2.625 V for monitoring input power rails. The device provides an active-high, push-pull output signal to indicate valid or invalid supply conditions. It includes a minimum reset timeout of 150 ms to ensure stable system recovery. The component is designed for surface-mount installation in the SOT-23-3 package and supports industrial operating temperatures from -40°C to +85°C.

Supervisors Feature Summary

• Provides hardware-based supervision of a single voltage rail with a fixed threshold
• Delivers a deterministic reset response via an active-high push-pull output
• Ensures system stability through a guaranteed minimum reset delay period

Supervisors Applications

• Monitoring microcontroller power supplies in embedded systems
• Supervising logic circuits requiring defined reset timing
• Industrial control units operating in extended temperature environments

Supervisors Procurement Notes

Verify the specific suffix '270' confirms the 2.625 V threshold requirement for your design. Confirm the '/TT' designation matches the required tape-and-reel packaging format. Ensure the 'I' grade aligns with the necessary industrial temperature range specifications. Cross-reference the manufacturer part number against official Microchip documentation to avoid counterfeit components.

Supervisors Selection Notes

Select this component when a fixed threshold voltage is sufficient without programmable adjustment. Choose the active-high push-pull output configuration if direct interfacing with digital inputs is required without external pull-up resistors. Consider the SOT-23-3 package constraints regarding board space and thermal dissipation requirements for the target application.

Supervisors Part Context

This part belongs to the MCP810 series of simple reset supervisor circuits. It is distinct from the MCP130 series, which typically utilizes open-drain outputs and different threshold options. The MCP810 family focuses on providing robust reset signals with minimal external component requirements for basic power management tasks.

Supervisors Replacement Considerations

Direct substitutes include other MCP810 variants with compatible thresholds and output types. Verify pinout compatibility before replacing with similar supervisory ICs from different manufacturers.
