MAX6339LUT+T

Overview

The MAX6339LUT+T is a quad voltage supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 2.5 V to 5.5 V and features four independent monitoring channels with thresholds including 1.8 V, 2.5 V, 3.3 V, and 5 V. The device provides an active-low open-drain reset output with a typical reset delay time of 200 ms. It draws a maximum quiescent current of 35 uA and maintains accuracy within 5%. The component is housed in a compact SOT-23-6 package and supports operation across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Integrates four independent voltage monitoring channels for comprehensive power system supervision
• Provides an active-low open-drain reset signal with configurable threshold detection
• Operates with low quiescent current consumption suitable for battery-powered applications

Applications

• Multi-rail embedded systems requiring simultaneous voltage supervision
• Portable electronic devices utilizing multiple logic voltage levels
• Industrial control units needing reliable power-fail detection

Procurement Notes

Verify the specific suffix configuration against official datasheets to ensure correct threshold voltages and package type. Confirm RoHS compliance status and lead times through authorized distributors. Check for obsolescence notices or lifecycle changes directly from Analog Devices documentation before finalizing procurement plans.

Selection Notes

Select this component when designing circuits requiring four distinct voltage monitoring points within a single IC footprint. Ensure the required threshold voltages match the available factory-set options or adjustable configurations. Verify that the open-drain output interface is compatible with the downstream microprocessor reset input requirements.

Part Context

This part belongs to the MAX6339P series of quad voltage supervisors. It complements other Maxim Integrated PMIC solutions by offering multi-channel monitoring in a small form factor. The series is designed to replace discrete comparator-based monitoring circuits, simplifying board layout and reducing component count in complex power architectures.

Replacement Considerations

Consult official cross-reference guides for verified substitutes. Ensure replacement parts maintain identical pinout compatibility and threshold specifications.
