MAX6326UR29

Supervisors Overview

The MAX6326UR29 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 2.93V. The device features an active-low, push-pull/totem-pole reset output and provides a minimum reset timeout period of 100ms. It operates within a temperature range of -40°C to +85°C and is available in surface-mount packages including SOT-23-3 and SC-70-3.

Supervisors Feature Summary

• Monitors a single power supply channel for undervoltage conditions
• Provides a guaranteed minimum reset timeout period after power rises above the threshold
• Features an active-low push-pull reset output stage

Supervisors Applications

• Microprocessor system power supervision
• Embedded controller power monitoring
• Portable electronic device power management

Supervisors Procurement Notes

Verify the specific package variant (SOT-23-3 or SC-70-3) required for your design, as availability may vary between distributors. Confirm that the 2.93V threshold aligns with your system's operating voltage requirements. Ensure compatibility with your PCB footprint and reflow soldering profile specifications.

Supervisors Selection Notes

Select this component when a fixed 2.93V threshold is appropriate for the monitored rail. Consider the push-pull output capability if driving logic inputs directly without external pull-ups. Evaluate the 100ms minimum timeout against your system's startup sequence timing requirements to ensure valid reset assertion.

Supervisors Part Context

This part belongs to the MAX6326 series of ultra-low-power microprocessor reset circuits. These devices are designed to monitor power-supply voltages while consuming minimal current. The series offers various threshold voltages and output configurations to suit different digital system applications requiring reliable power supervision.

Supervisors Replacement Considerations

The ADM6326-29ARTZ-R7 serves as a direct equivalent from Analog Devices, offering identical electrical characteristics and functionality. Verify pinout compatibility and package dimensions before substitution to ensure seamless integration into existing designs.
