MAX6355LSUT-T

Overview

The MAX6355LSUT-T is a dual/triple-voltage microprocessor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It monitors up to three power supply rails and provides reset signals via an active-low, open-drain output. The device features a manual reset input and operates within a supply voltage range of up to 5.5 V. It includes a fixed reset delay time of 180 ms and maintains an accuracy of 1.5%. The component is designed for surface-mount installation in SOT-23-6 packages and supports operation across temperatures from -40°C to +85°C.

Feature Summary

• Monitors multiple voltage rails with configurable thresholds
• Provides active-low open-drain reset output
• Includes manual reset input capability
• Operates with low quiescent current consumption

Applications

• Microprocessor system power supervision
• Portable equipment voltage monitoring
• Battery-powered device protection

Procurement Notes

Verify the exact suffix configuration against official datasheets, as variations exist within the MAX6355 family. Confirm availability status directly with authorized distributors, as this specific part number may be subject to discontinuation or limited stock constraints. Ensure compatibility with existing PCB footprints and thermal requirements before finalizing procurement decisions.

Selection Notes

Select this component when simultaneous monitoring of two or three distinct voltage levels is required without watchdog functionality. Consider the 180 ms reset delay and 1.5% threshold accuracy for timing-sensitive applications. Verify that the SOT-23-6 package fits the design constraints and that the operating temperature range meets environmental specifications.

Part Context

This part belongs to the MAX6355 series of voltage supervisors, which are designed for general-purpose microprocessor reset generation. The series offers various threshold combinations and package options to accommodate different system architectures. The LSUT variant specifically denotes a particular set of threshold voltages and packaging style within this broader product line.

Replacement Considerations

Check for direct pin-compatible alternatives within the MAX6355 family with matching threshold voltages. Verify if newer generations from Analog Devices offer improved performance or availability while maintaining functional equivalence.
