MAX6339PUT+T

Overview

The MAX6339PUT+T is a quad voltage supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It monitors four independent power supply rails using an SOT-23-6 surface-mount package. The device features active-low, open-drain outputs with a reset delay time of 200 ms. It operates within a supply voltage range up to 5.5 V and maintains accuracy within 5%. The component supports threshold voltages including -5 V, 3.3 V, 5 V, and adjustable settings, functioning reliably across a temperature range of -40°C to +85°C.

Feature Summary

• Monitors four independent voltage inputs simultaneously
• Provides active-low open-drain reset signals
• Includes a fixed 200 ms reset delay timer
• Operates with low quiescent current consumption

Applications

• Multi-rail power system supervision in embedded systems
• Voltage monitoring for microprocessor reset sequences
• Industrial control board power integrity verification
• Communication equipment power rail validation

Procurement Notes

Verify the specific suffix configuration against official datasheets to ensure correct threshold voltage selection and package type compatibility. Confirm RoHS compliance status and manufacturing origin through authorized distributors. Check for obsolescence notices or lifecycle changes prior to finalizing procurement plans to avoid supply chain disruptions.

Selection Notes

Select this component when simultaneous monitoring of four distinct voltage levels is required in space-constrained designs. The SOT-23-6 package offers a compact footprint suitable for dense PCB layouts. Ensure the application voltage ranges align with the available fixed and adjustable threshold options provided by the device architecture.

Part Context

This part belongs to the MAX6339P series of multi-voltage supervisors designed for portable and industrial applications. It integrates multiple monitor channels into a single small outline transistor package, reducing component count compared to discrete solutions. The series emphasizes low power consumption and high accuracy for reliable system protection.

Replacement Considerations

Consult the manufacturer's cross-reference guide for direct pin-compatible alternatives. Verify that any substitute component matches the SOT-23-6 package dimensions and electrical characteristics such as reset delay and output drive capability.
