MAX6339KUT-T

Overview

The MAX6339KUT-T is a quad voltage supervisor from Analog Devices Inc./Maxim Integrated, designed for monitoring four independent power rails. It operates within a supply voltage range of 1V to 5.5V and features an SOT-23-6 surface-mount package. The device provides active-low reset outputs with open-drain or open-collector configurations. Key electrical parameters include a reset timeout of 140ms and threshold voltages such as 2.19V, 2.93V, and adjustable settings. It functions reliably across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Monitors four distinct voltage inputs simultaneously
• Provides active-low reset signal generation
• Features open-drain or open-collector output structure
• Operates with low supply voltage requirements

Applications

• Portable equipment power management
• Battery-powered system supervision
• Embedded controller power rail monitoring
• Industrial control unit voltage tracking

Procurement Notes

Verify the exact suffix configuration against official datasheets, as variations exist between K, H, and C variants. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability fluctuates. Ensure the specific threshold voltage options match your design requirements before ordering.

Selection Notes

Select this component when multiple voltage rails require simultaneous supervision in a compact footprint. Consider the open-drain output capability for wired-OR connections. Verify that the 140ms reset timeout aligns with system startup timing requirements. Ensure the operating temperature range meets environmental conditions.

Part Context

This part belongs to the MAX6339 series of quad voltage supervisors. It shares functional similarities with other Maxim Integrated supervisory circuits but offers specific threshold combinations. The SOT-23-6 package allows for space-constrained designs compared to larger packages.

Replacement Considerations

Check for direct pin-compatible alternatives within the MAX6339 family, such as MAX6339HUT+T or MAX6339CUT+T, which may offer different threshold voltages. Verify that any substitute maintains the same output type and reset timeout characteristics.
