MAX6327UR30

Overview

The MAX6327UR30+T is a 3-pin ultra-low-power microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It monitors a single voltage input with a threshold of 3.0V and an overvoltage threshold of 3.045V. The device features an active-high, push-pull output type and provides a reset delay time of 280 ms. It operates within a supply voltage range up to 5.5 V and consumes only 500 nA of working power current. The component is housed in an SC-70-3 package and functions reliably across a temperature range from -40°C to +85°C.

Feature Summary

• Ultra-low power consumption with 500 nA operating current
• Active-high push-pull reset output for direct logic interfacing
• Compact SC-70-3 surface-mount packaging

Applications

• Portable equipment requiring extended battery life
• Microprocessor system power supervision
• Digital system voltage monitoring

Procurement Notes

Verify the specific suffix UR30 against official datasheets to confirm the 3.0V threshold and SC-70-3 package configuration. Confirm RoHS compliance status through manufacturer documentation. Check current availability as distribution channels may list limited stock or end-of-life statuses for this specific part number variant.

Selection Notes

Select this component when an active-high reset signal is required for digital logic compatibility. The low quiescent current makes it suitable for battery-operated devices where power efficiency is critical. Ensure the monitored voltage aligns with the 3.0V threshold specification and that the SC-70-3 footprint fits the design constraints.

Part Context

This part belongs to the MAX6327X series of microprocessor supervisory circuits designed for portable applications. It shares family characteristics such as ultra-low power operation and compact packaging with other variants like the MAX6326 and MAX6328, differing primarily in output polarity and threshold voltage settings.

Replacement Considerations

Consider the MAX6327XR25+T for similar functionality with a 2.5V threshold. Verify pinout compatibility and output polarity requirements before substituting with other MAX6327 series variants.
