MAX6351UVUT+T

Overview

The MAX6351UVUT+T is a dual voltage supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It monitors two independent power supply rails and provides a reset signal when voltages fall below or exceed specified thresholds. The device features an active-low, open-drain output and includes a manual reset input for system control. It operates within a temperature range of -40°C to +85°C and is housed in a compact SOT-23-6 surface-mount package.

Feature Summary

• Dual-channel voltage monitoring with configurable threshold detection
• Active-low open-drain reset output compatible with various logic families
• Manual reset input allows external assertion of the reset state
• Compact SOT-23-6 packaging suitable for space-constrained designs

Applications

• Portable electronic devices requiring multi-rail power supervision
• Embedded systems needing reliable brown-out protection
• Industrial control units operating in extended temperature environments
• Communication equipment requiring stable power sequencing

Procurement Notes

Verify component authenticity through authorized distributors due to availability constraints. Confirm RoHS compliance status and check for obsolescence notices from Analog Devices. Ensure storage conditions meet moisture sensitivity level requirements before assembly. Validate pinout compatibility with existing PCB layouts during integration planning.

Selection Notes

Evaluate threshold voltage accuracy against system requirements before implementation. Consider the open-drain output configuration for pull-up resistor selection. Assess manual reset functionality needs versus automatic recovery options. Compare package dimensions against available board space constraints.

Part Context

This component belongs to the MAX635x series of microprocessor supervisory circuits designed for low-power applications. The UV suffix indicates specific threshold voltage characteristics within the family. These devices are engineered for reliability in consumer and industrial electronics where power integrity is critical.

Replacement Considerations

Cross-reference with MAX6351LTUT+T or MAX6351TZUT+T for similar dual-supervisor functions. Verify threshold voltage compatibility when substituting variants within the MAX6351 family. Check package pinout alignment to ensure direct replacement feasibility without PCB modifications.
