MAX6355RVUT+T

Overview

The MAX6355RVUT+T is a triple-voltage supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It monitors three independent voltage rails with thresholds of 1.58V, 2.63V, and an adjustable third channel. The device features an active-low open-drain reset output and a manual reset input. It operates within a supply voltage range up to 5.5V and includes a fixed reset timeout delay of 100ms minimum. Packaged in a compact SOT-23-6 surface-mount case, it supports operation from -40°C to +85°C.

Feature Summary

• Monitors three distinct power supply voltages simultaneously
• Includes an adjustable threshold for the third monitoring channel
• Provides active-low open-drain reset signal generation
• Supports manual reset functionality via dedicated input pin

Applications

• Multi-rail embedded system power supervision
• Portable electronic device voltage monitoring
• Industrial control board power integrity verification

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential counterfeit risks. Confirm package marking and datasheet revision match the specific lot code. Check end-of-life status as some variants may be discontinued. Ensure environmental compliance documentation aligns with project requirements before finalizing procurement decisions.

Selection Notes

Select this component when simultaneous monitoring of three voltage levels is required in space-constrained designs. The adjustable threshold offers flexibility for non-standard rail voltages. Verify that the open-drain output configuration matches the downstream logic interface requirements. Ensure the operating temperature range covers the intended application environment conditions.

Part Context

This part belongs to the MAX6355L series of dual/triple-voltage supervisors. It shares functional similarities with other Maxim Integrated supervisory ICs but is distinguished by its triple-channel capability and adjustable threshold feature. The RVUT suffix indicates specific threshold values and packaging type within the broader product family.

Replacement Considerations

Direct substitutes include MAX6355LSUT+T and MAX6358LTUT+T, though pinout and threshold configurations differ. Verify compatibility with existing PCB layout and software reset handling before substitution.
