MAX6355MSUT+T

Overview

The MAX6355MSUT+T is a dual/triple-voltage microprocessor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It monitors up to three input voltages and provides an active-low, open-drain reset output with a manual reset capability. The device operates within a supply voltage range of up to 5.5 V and features a typical reset delay time of 180 ms. It is available in a compact SOT-23-6 surface-mount package and supports operation across a temperature range of -40°C to +85°C.

Feature Summary

• Monitors multiple power rails for system stability
• Provides manual reset functionality via dedicated pin
• Features low quiescent current consumption for efficiency

Applications

• Portable electronic devices requiring multi-rail supervision
• Embedded systems needing voltage monitoring
• Industrial control units operating in extended temperatures

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential counterfeits. Confirm RoHS compliance status and specific lot traceability requirements before procurement. Note that this part may be subject to end-of-life restrictions; check current lifecycle status and availability constraints with the supplier prior to ordering.

Selection Notes

Select this component when simultaneous monitoring of two or three distinct voltage levels is required in space-constrained designs. Ensure the threshold voltages match the specific rails being monitored. Consider the SOT-23-6 package size relative to board layout constraints and verify that the active-low open-drain output interface is compatible with the target microprocessor's reset input logic.

Part Context

This supervisor belongs to the MAX6355M series, designed for low-power applications. It complements other Maxim Integrated voltage supervisors by offering triple-channel monitoring in a minimal footprint. The series is commonly used in battery-powered and portable equipment where power management integrity is critical for reliable system operation.

Replacement Considerations

Check for MAX6355MRUT+T as a potential variant with similar specifications but different threshold options. Verify pin compatibility and electrical parameters against datasheets before substitution. No direct cross-reference is confirmed without explicit manufacturer documentation.
