MAX6339MUT+T

Overview

The MAX6339MUT+T is a quad voltage supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It monitors four distinct power rails using fixed and adjustable thresholds, including 2.63V, 4.38V, and an adjustable setting. The device features an active-low open-drain reset output with a minimum reset delay of 140ms. Operating within a supply range up to 5.5V, it consumes low quiescent current and functions reliably across a temperature range of -40°C to +85°C. Packaged in a compact SOT-23-6 surface-mount format, it provides precise monitoring for multi-voltage systems.

Feature Summary

• Monitors four independent voltage inputs simultaneously
• Provides active-low open-drain reset signal generation
• Supports fixed and adjustable threshold configurations
• Operates without manual reset or watchdog timer functionality

Applications

• Multi-rail embedded system power supervision
• Portable electronic device voltage monitoring
• Industrial control board power integrity verification
• Telecommunications equipment power rail tracking

Procurement Notes

Verify the exact suffix configuration against official datasheets to ensure correct threshold selection. Confirm package type matches design requirements. Check RoHS compliance status for regulatory adherence. Validate operating temperature range suitability for the target environment. Ensure pinout compatibility with existing PCB footprints before integration.

Selection Notes

Select this component when simultaneous monitoring of four voltages is required in a small footprint. Consider the adjustable threshold option if specific voltage levels are needed beyond standard values. Evaluate the 140ms minimum reset delay against system startup timing requirements. Compare quiescent current consumption against battery life constraints in portable applications.

Part Context

This part belongs to the MAX6339P series of quad voltage supervisors. It shares functional similarities with other Maxim integrated circuit monitoring solutions but offers specific threshold combinations. The series is designed for applications requiring reliable power management without complex external components. It complements other PMIC offerings from Analog Devices for comprehensive system protection.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with alternative quad supervisors based on threshold accuracy and package dimensions. Cross-reference electrical specifications carefully to ensure equivalent performance in critical monitoring roles.
