MAX6355SVUT+T

Overview

The MAX6355SVUT+T is a dual/triple-voltage microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It monitors up to three input voltages within a supply range of 1.2V to 5.5V, housed in an SOT-23-6 surface-mount package. The device features active-low open-drain outputs with a fixed reset delay time of 180ms and offers high accuracy of 1.5%. It operates across an extended temperature range from -40°C to +85°C while consuming only 20µA of quiescent current.

Feature Summary

• Monitors multiple power rails simultaneously using factory-set threshold levels
• Provides low-active open-drain reset signals for system reliability
• Includes manual reset input compatible with TTL/CMOS logic

Applications

• Embedded systems requiring multi-rail voltage supervision
• Portable electronic devices with limited power budgets
• Industrial control units operating in extended temperature environments

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential availability constraints. Confirm RoHS compliance status and specific lot traceability requirements before procurement. Ensure the ordering suffix matches the required voltage thresholds and package configuration exactly as specified in the official datasheet to avoid functional mismatches.

Selection Notes

Select this component when simultaneous monitoring of two or three distinct voltage rails is required without external comparator circuits. The fixed 180ms reset delay suits applications where rapid recovery is not critical but stability is paramount. Consider the 20µA quiescent current for battery-operated designs and verify that the open-drain output interface aligns with the target microprocessor's reset pin requirements.

Part Context

This part belongs to the MAX6355 series of microprocessor supervisors designed for cost-sensitive and space-constrained applications. The series provides integrated solutions for power management by replacing discrete components. The SVUT+T designation indicates specific voltage thresholds and tape-and-reel packaging suitable for automated surface-mount assembly processes.

Replacement Considerations

Consult the official MAX6355 family datasheet for cross-reference options. Verify that any substitute maintains identical pinout compatibility, voltage thresholds, and output drive characteristics to ensure seamless integration without schematic modifications.
