MAX6351UVUT+

Overview

The MAX6351UVUT+ is a dual microprocessor supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It monitors two independent voltage rails and provides active-low reset outputs referenced to VCC1 and VCC2 respectively. The device features a debounced manual reset input and operates within an extended temperature range of -40°C to +85°C. It is housed in a compact SOT-23-6 surface-mount package, designed for high reliability in systems requiring precise power supply supervision.

Feature Summary

• Dual-channel monitoring with independent reset outputs referenced to respective supply rails
• Active-low push-pull reset outputs ensure compatibility with standard logic families
• Debounced manual reset input allows for controlled system initialization
• Extended industrial temperature rating supports operation in harsh environments

Applications

• Multi-rail embedded system power management
• Industrial control unit voltage supervision
• Telecommunications equipment power integrity monitoring

Procurement Notes

Verify component authenticity through authorized distributors due to potential counterfeit risks. Confirm RoHS compliance status matches specific manufacturing lot requirements. Check datasheet revisions for any pinout or electrical characteristic updates before finalizing integration into production designs.

Selection Notes

Select this component when simultaneous supervision of two distinct voltage domains is required. Ensure threshold voltages align with target rail specifications. Consider the SOT-23-6 footprint constraints during PCB layout planning. Verify that the active-low output polarity meets downstream controller input requirements.

Part Context

Part of the MAX6351-MAX6360 family of multi-voltage supervisors. This series improves system reliability over discrete solutions by integrating precision thresholds and manual reset functionality into a single compact package. The UV suffix indicates specific voltage threshold configurations within the broader product line.

Replacement Considerations

Cross-reference with MAX6351LTUT+T or MAX6351TZUT+T for similar dual-supervision capabilities. Verify threshold voltage compatibility and package pinout alignment before substitution. Consult official replacement guides for end-of-life transitions.
