MAX6355MSUT

Overview

The MAX6355MSUT+T is a dual/triple-voltage microprocessor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It operates within a supply voltage range of up to 5.5 V and features an active low, open-drain output type with manual reset capability. The device monitors three inputs and includes specific threshold voltages of 2.63 V and 4.38 V, along with overvoltage thresholds of 2.68 V and 4.46 V. It exhibits a reset delay time of 180 ms and maintains an accuracy of 1.5%. The component draws a working power supply current of 20 uA and dissipates 695 mW. It functions reliably between -40 C and +85 C in a SOT-23-6 package.

Feature Summary

• Provides simultaneous supervision for multiple voltage rails using a compact surface-mount design
• Integrates a manual reset input for controlled system initialization sequences
• Delivers precise voltage monitoring with defined threshold and overvoltage detection levels

Applications

• Embedded systems requiring multi-rail power supervision
• Microprocessor-based control units needing reliable reset generation
• Industrial equipment operating in extended temperature environments

Procurement Notes

Verify the exact suffix configuration against official datasheets to ensure correct threshold voltage selection. Confirm availability status as distribution channels may indicate limited stock or discontinuation. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and traceability before finalizing procurement decisions.

Selection Notes

Select this component when designing circuits that require monitoring of three distinct voltage lines simultaneously. Ensure the required threshold voltages align with the available options in the MAX6355 series. Consider the SOT-23-6 package constraints for PCB layout and verify that the 180 ms reset delay meets the system timing requirements.

Part Context

This component belongs to the MAX6355M series of supervisory circuits from Maxim Integrated. It is designed specifically for applications demanding high accuracy and low power consumption. The series offers various threshold combinations to accommodate different standard voltage rails commonly found in digital logic and memory systems.

Replacement Considerations

Check for other variants within the MAX6355 family that offer compatible threshold voltages if the MSUT suffix is unavailable. Verify pin compatibility and electrical specifications before substituting with similar supervisory ICs from other manufacturers.
