MAX6339CUT+T

Overview

The MAX6339CUT+T is a quad voltage supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It monitors four independent power supply rails using a BICMOS technology in a SOT-23-6 surface-mount package. The device provides active-low, open-drain reset outputs with a typical reset delay of 200 ms. It operates within a supply voltage range of 1 V to 5.5 V and features an accuracy of 5%. The component supports threshold voltages including fixed options like 3.3 V and 5 V, as well as adjustable settings, ensuring reliable system protection across industrial temperature ranges from -40°C to +85°C.

Feature Summary

• Monitors four independent voltage inputs simultaneously for comprehensive power integrity management
• Generates active-low reset signals via open-drain outputs to interface with microprocessor logic
• Utilizes low-power BICMOS technology to minimize current consumption during operation

Applications

• Multi-rail embedded system power supervision
• Industrial control unit voltage monitoring
• Telecommunications equipment power integrity verification

Procurement Notes

Verify the specific suffix configuration against official datasheets to confirm exact threshold voltage selections and package variations. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability may vary by region. Ensure the ordering part number matches the required electrical specifications and thermal performance criteria for the target application environment.

Selection Notes

Select this component when simultaneous monitoring of four distinct voltage rails is required within a compact SOT-23-6 footprint. Consider the 5% accuracy specification and 200 ms reset delay to ensure compatibility with downstream processor timing requirements. Evaluate the operating temperature range and supply voltage limits to verify suitability for the intended environmental conditions and power architecture.

Part Context

This component belongs to the MAX6339P series of quad voltage supervisors designed for applications requiring multi-channel power monitoring. It integrates multiple supervisory channels into a single small-outline package, reducing board space compared to discrete solutions. The series is engineered for reliability in systems where power stability is critical for maintaining operational integrity.

Replacement Considerations

Consult official cross-reference lists for verified substitutes such as other MAX6339 variants with different suffixes or equivalent quad supervisors from Analog Devices. Verify pinout compatibility and electrical parameter alignment before substitution.
