MAX6327UR22-T

Supervisors Overview

The MAX6327UR22-T is a microprocessor supervisory circuit featuring an active-high, push-pull reset output. It monitors a single voltage input with a fixed threshold of 2.2V. The device operates within a supply range of 1V to 5.5V and provides a minimum power-on reset pulse width of 100ms. It draws a maximum supply current of 1µA. The component is housed in a 3-pin SC70 or SOT-23 package.

Supervisors Feature Summary

• Active-high push-pull reset output for direct logic interface
• Ultra-low supply current suitable for portable equipment
• Factory-trimmed precision voltage monitoring threshold

Supervisors Applications

• Microprocessor system supervision
• Portable digital systems
• Battery-powered devices requiring low quiescent current

Supervisors Procurement Notes

Verify the obsolete status of this specific suffix variant against current Analog Devices inventory. Confirm that the +T suffix version is available if manufacturing continuity is required. Ensure the package type matches the design footprint requirements before ordering.

Supervisors Selection Notes

Select this part when an active-high output is required, as opposed to the active-low variants in the same family. The 2.2V threshold is fixed; verify compatibility with the target system's brown-out detection level. Consider the 1µA current draw for battery life calculations in always-on applications.

Supervisors Part Context

This component belongs to the MAX6326/MAX6327/MAX6328 series of ultra-low-power reset circuits. These devices eliminate external components by integrating precise voltage monitoring and timing functions into a small 3-pin package, designed for reliability in digital systems powered by 2.5V, 3V, 3.3V, and 5V supplies.

Supervisors Replacement Considerations

Publicly confirmed substitutes include other MAX6327 variants with different thresholds (e.g., MAX6327UR29) or the MAX6347 series. Verify pinout compatibility and output polarity before substitution.
