MAX6327UR28+T

Overview

The MAX6327UR28+T is a single-channel power supply support circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a voltage range of 1.6V to 5.5V with a fixed threshold of 2.8V. The device features an active-low, open-drain output and provides a reset timeout of 140ms minimum. It functions in temperatures from -40°C to +85°C and consumes only 500nA of quiescent current. Packaged in a compact SOT-23-3 surface-mount case, it supports standard reflow soldering processes.

Feature Summary

• Ultra-low power consumption suitable for battery-operated systems
• Fixed voltage threshold monitoring for reliable system supervision
• Compact three-pin surface-mount packaging for space-constrained designs

Applications

• Portable electronic devices requiring low standby current
• Battery-powered instrumentation and sensors
• Embedded systems needing simple power-on reset functionality

Procurement Notes

Verify the specific suffix UR28 corresponds to the required 2.8V threshold and SOT-23-3 package configuration. Confirm RoHS compliance status and lead-free certification requirements against project specifications. Ensure the ordering part number matches the exact manufacturer designation to avoid functional mismatches in critical supervisory circuits.

Selection Notes

Select this component when a fixed 2.8V supervision level is required without manual reset capabilities. Consider the ultra-low quiescent current for extended battery life applications. Verify that the open-drain output interface aligns with the downstream logic voltage levels and pull-up resistor requirements of the target system design.

Part Context

This component belongs to the MAX6327 series of ultra-low-power voltage supervisors. It serves as a fundamental building block for power management architectures where precise voltage monitoring is essential. The series offers various threshold options to accommodate different rail voltages while maintaining consistent performance characteristics across the product line.

Replacement Considerations
