MAX6326UR28

Supervisors Overview

The MAX6326UR28+T is a microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It monitors a single power supply channel with a fixed reset threshold voltage of 2.8V. The device features an active-low push-pull/totem-pole output and provides a minimum reset timeout period of 100ms. It operates within a temperature range of -40°C to +85°C and is housed in a surface-mount SOT-23-3 package.

Supervisors Feature Summary

• Monitors a single power supply channel for undervoltage conditions
• Provides active-low reset signal via push-pull output stage
• Ensures valid reset down to 1V supply voltage
• Designed to ignore fast negative transients on VCC

Supervisors Applications

• Microprocessor system power supervision
• Battery-powered equipment monitoring
• Portable instrumentation reset circuits

Supervisors Procurement Notes

Verify the complete part number including suffixes such as '+T' for tape-and-reel packaging when ordering. Confirm that the specific threshold voltage (2.8V) matches the design requirements. Check current availability status as distribution may vary. Ensure compliance with RoHS3 specifications if required by the target application environment.

Supervisors Selection Notes

Select this component when a fixed 2.8V threshold is required for single-channel monitoring. Compare against other MAX6326 variants with different thresholds or output types like open-drain. Consider the SOT-23-3 package size constraints. Verify that the 100ms minimum timeout meets the system's power-up sequence requirements.

Supervisors Part Context

This part belongs to the MAX6326-MAX6328 family of ultra-low-power reset circuits. These devices are designed for applications requiring reliable power management in compact form factors. The family offers various threshold voltages and output configurations to suit different microprocessor and memory systems.

Supervisors Replacement Considerations

Direct substitutes include other MAX6326 series parts with identical 2.8V thresholds and push-pull outputs, such as MAX6326UR28+T. Cross-family replacements from other manufacturers require verification of pin compatibility and electrical parameters.
