MAX6338MUB+T

Overview

The MAX6338MUB+T is a quad voltage monitor from Analog Devices/Maxim Integrated, housed in a 10-UMAX package. It monitors four distinct supply rails with thresholds of 2.63 V, 4.38 V, adjustable, and -4.38 V. The device features active-low open-drain outputs and operates within a supply range of 2.5 V to 5.5 V. It draws 35 µA of quiescent current and functions between -40°C and +85°C.

Feature Summary

• Monitors four independent voltage inputs simultaneously
• Provides active-low open-drain reset signals for each channel
• Includes an adjustable threshold input for custom monitoring

Applications

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

Procurement Notes

Verify the specific suffix against official documentation to confirm exact threshold configurations and package variations. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer before procurement planning.

Selection Notes

Select this component when simultaneous monitoring of four distinct voltage levels is required. Ensure the available threshold options match the target rails. Verify that the open-drain output configuration aligns with the downstream logic requirements.

Part Context

This part belongs to the MAX6338 series of quad voltage supervisors. It provides compact multi-channel monitoring solutions for applications requiring precise oversight of multiple power domains within a small surface-mount footprint.

Replacement Considerations

Direct substitutes include other MAX6338 variants such as MAX6338IUB+T or MAX6338PUB+, provided their fixed threshold values match the application requirements.
