MAX6355TZUT-T

Overview

The MAX6355TZUT+T is a dual/triple-voltage microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It monitors three input voltages with thresholds of 2.32 V and 3.08 V, featuring an active low open-drain output and manual reset capability. The device operates within a supply voltage range up to 5.5 V, consumes 20 uA, and maintains 1.5% accuracy. It provides an 180 ms reset delay and functions reliably between -40°C and +85°C in a compact SOT-23-6 package.

Feature Summary

• Monitors multiple power rails simultaneously using dedicated threshold inputs for precise voltage supervision.
• Provides manual reset functionality allowing external control over the system reset state via a dedicated pin.
• Delivers active low open-drain outputs suitable for interfacing with various logic families without level shifting requirements.

Applications

• Portable equipment requiring multi-rail power monitoring
• Battery-powered systems needing low quiescent current supervision
• Embedded controllers requiring manual reset override capabilities

Procurement Notes

Verify the exact suffix configuration against official datasheets, as variations exist within the MAX6355 family. Confirm availability status through authorized distributors, as some variants may be discontinued or subject to allocation. Ensure the selected part matches the required threshold voltages and package type for your specific design implementation.

Selection Notes

Select this component when simultaneous monitoring of two or three distinct voltage levels is required with high accuracy. The low 20 uA operating current makes it suitable for battery-operated devices where standby power consumption is critical. Verify that the open-drain output architecture aligns with your system's pull-up resistor strategy and logic interface requirements.

Part Context

This component belongs to the MAX6355 series of microprocessor supervisors designed for portable applications. It offers configurable threshold voltages and manual reset options within a small SOT-23-6 footprint. The series supports various combinations of monitored voltages to accommodate diverse power management architectures in consumer electronics and industrial controls.

Replacement Considerations

Check for direct substitutes within the MAX6355 family with matching threshold specifications. Consider the MAX6355MRUT+T or MAX6355LTUT+T if different voltage thresholds are acceptable. Verify pin compatibility and electrical characteristics before substituting any alternative supervisor ICs.
