MAX6351RVUT

Overview

The MAX6351RVUT+T is a dual voltage microprocessor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It operates within a supply voltage range of 2.0V to 5.5V and features two independent voltage monitoring channels with thresholds of 2.63V and 4.38V. The device provides an active-low open-drain reset output with a fixed 180ms reset delay time. It includes a manual reset input for system control and operates without a watchdog timer or battery backup switch. The component is housed in a compact SOT-23-6 surface-mount package, ensuring reliable supervision for embedded systems.

Feature Summary

• Dual-channel voltage monitoring with configurable threshold levels
• Active-low open-drain reset output with fixed delay
• Manual reset input capability for system control

Applications

• Microprocessor power supply supervision
• Embedded system voltage monitoring
• Portable electronic device power management

Procurement Notes

Verify the exact suffix configuration against official datasheets, as variations exist within the MAX6351 family. Confirm availability status through authorized distributors, as specific variants may be discontinued or subject to limited supply constraints. Ensure compatibility with existing PCB footprints and thermal requirements before finalizing procurement decisions.

Selection Notes

Select this component when dual independent voltage rails require simultaneous supervision within a single package. The fixed 180ms delay suits applications where immediate reset upon brownout is not critical. Verify that the required threshold voltages match the available factory-set options or consider adjustable alternatives if custom thresholds are necessary.

Part Context

This part belongs to the MAX635x series of low-power microprocessor supervisors designed for portable and industrial applications. The series offers various channel configurations and threshold combinations to accommodate diverse power architecture needs while maintaining a small footprint and low quiescent current consumption.

Replacement Considerations

Cross-reference with other MAX6351 variants such as MAX6351UVUT+T or MAX6351TZUT+T for different threshold settings. Verify pinout compatibility and electrical specifications before substituting.
