MAX6339EUT+T

Overview

The MAX6339EUT+T is a quad voltage supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It monitors four independent supply voltages and provides reset signals when thresholds are exceeded. The device operates within a supply voltage range of 1 V to 5.5 V and features an active low, open-drain output. It includes a fixed reset delay time of 200 ms and maintains accuracy within 5%. The component is housed in a compact SOT-23-6 package and supports surface mount installation.

Feature Summary

• Monitors four independent power supply rails simultaneously
• Provides active low reset signal via open-drain output
• Includes fixed 200 ms reset delay timer for stability

Applications

• Multi-rail power system supervision
• Embedded controller power monitoring
• Industrial equipment voltage tracking

Procurement Notes

Verify the specific threshold voltage configuration required for the EUT suffix variant against official datasheets before procurement. Confirm RoHS compliance status and lead times with authorized distributors, as availability may vary. Ensure the SOT-23-6 footprint matches the design layout requirements.

Selection Notes

Select this component when simultaneous monitoring of four distinct voltage levels is necessary. The open-drain output allows for wired-OR configurations or interfacing with various logic families. Consider the 5% accuracy specification and 200 ms delay for timing-sensitive applications requiring stable power sequencing.

Part Context

This part belongs to the MAX6339P series of quad voltage supervisors. It is designed for applications requiring comprehensive power management without external components. The series offers multiple threshold options to accommodate different standard voltage rails commonly found in digital systems.

Replacement Considerations

Check for direct pin-compatible alternatives within the MAX6339 family that match the specific threshold requirements. Verify if newer generations from Analog Devices offer improved accuracy or lower quiescent current while maintaining the same package outline.
