MCP6571T-E/OT

Comparators Overview

The MCP6571T-E/OT is a single-channel window analog comparator manufactured by Microchip Technology. It operates within a supply voltage range of 1.8 V to 5.5 V and features rail-to-rail inputs with push-pull outputs. Key electrical specifications include an input offset voltage of 7 mV, a common-mode rejection ratio of 54 dB, and a power supply rejection ratio of 60 dB. The device supports an operating temperature range from -40°C to +125°C and is housed in a SOT-23-5 surface-mount package.

Comparators Feature Summary

• Window comparator architecture for monitoring signal levels within defined thresholds
• Rail-to-rail input capability allowing operation across the full supply voltage range
• Push-pull output stage providing active drive in both high and low states

Comparators Applications

• Voltage level detection in battery-powered systems
• Threshold monitoring in industrial control circuits
• Over-voltage or under-voltage protection schemes

Comparators Procurement Notes

Verify the specific suffix /OT against the manufacturer's current datasheet to confirm package type and tape-and-reel specifications. Ensure the E temperature grade matches the required operational environment. Cross-reference the Mouser part number 579-MCP6571T-E/OT with official Microchip documentation to validate component authenticity and revision status before procurement.

Comparators Selection Notes

Select this component when a window comparison function is required rather than standard threshold switching. The push-pull output eliminates the need for external pull-up resistors found in open-drain alternatives. Verify that the 7 mV input offset voltage meets the precision requirements of the application circuit design.

Comparators Part Context

This device belongs to the MCP6571 family of analog comparators from Microchip Technology. The family includes variants with different output types and packages. The T-E/OT designation specifically indicates the tape-and-reel packaging format and the extended industrial temperature grade suitable for demanding electronic environments.

Comparators Replacement Considerations

MCP6571UT-E/LT is a documented substitute offering similar functionality in an SC-70-5 package.
