MAX6338OUB+TG069

Overview

The MAX6338OUB+TG069 is a quad voltage monitor from the MAX6338 series, manufactured by Analog Devices Inc./Maxim Integrated. It supervises four independent power rails within a 10-pin uMAX package. The device monitors inputs including fixed thresholds of 5 V, 3.3 V, and -4.38 V, alongside an adjustable threshold. It features active low, open-drain outputs with 2.5% accuracy. Operating from a maximum supply voltage of 5.5 V, it draws 35 µA and functions between -40°C and +85°C.

Feature Summary

• Monitors four independent voltage rails simultaneously
• Provides active low open-drain fault indication
• Includes fixed and adjustable threshold options
• Operates in industrial temperature ranges

Applications

• Multi-rail power system supervision
• Embedded system voltage monitoring
• Industrial control board protection

Procurement Notes

Verify the exact suffix configuration against official datasheets to ensure correct threshold settings. Confirm RoHS compliance status as some variants may differ. Check regional availability restrictions before ordering. Ensure the uMAX-10 package matches your PCB footprint requirements. Validate manufacturer authenticity through authorized channels.

Selection Notes

Select this component when simultaneous monitoring of multiple distinct voltage levels is required. The combination of fixed and adjustable thresholds offers flexibility for mixed-signal systems. Consider the low quiescent current for battery-sensitive applications. Verify that the open-drain output interface aligns with the downstream logic requirements.

Part Context

This part belongs to the MAX6338 family of supervisory circuits designed for reliable power management. It serves as a critical safety component in systems requiring strict voltage oversight. The uMAX package provides a compact solution for space-constrained designs while maintaining robust performance characteristics.

Replacement Considerations

Check for MAX6338OUB+ or MAX6338OUB+T as potential direct substitutes. Verify pin compatibility and threshold specifications before substitution. Ensure the replacement maintains the same package type and electrical characteristics.
