MAX6338PUB+

Overview

The MAX6338PUB+ is a quad voltage monitor manufactured by Analog Devices Inc./Maxim Integrated, designed for surface-mount installation in 10-UMAX packages. It operates within a supply voltage range of 2.5V to 5.5V and features four independent open-drain active-low outputs. The device monitors specific thresholds including -5V, 3.3V, 5V, and an adjustable input. It maintains a typical operating supply current of 35µA and ensures accuracy of 2.5%. The component supports a reset delay time of 1.12s and functions reliably across a temperature range of -40°C to +85°C.

Feature Summary

• Monitors up to four distinct power supply rails simultaneously without requiring external components
• Provides four independent open-drain active-low reset outputs for flexible system integration
• Includes a user-adjustable threshold input alongside fixed factory-trimmed voltage options

Applications

• Telecommunications equipment power supervision
• Desktop and notebook computer motherboard monitoring
• Data storage controller voltage tracking
• Industrial control system power integrity verification

Procurement Notes

Verify the specific suffix 'PUB+' against the manufacturer's official datasheet to confirm the exact threshold configuration. Ensure the 10-UMAX package dimensions match the target PCB footprint. Confirm RoHS compliance status with the supplier documentation prior to final procurement approval.

Selection Notes

Select this component when simultaneous monitoring of multiple standard logic levels and a negative rail is required. The adjustable channel allows customization for non-standard voltages. Consider the 35µA quiescent current for battery-sensitive designs. Verify that the open-drain output structure aligns with the downstream logic interface requirements.

Part Context

This part belongs to the MAX6338 family of quad voltage monitors from Maxim Integrated. The series is engineered for compact multi-supervisory applications where board space is limited. It replaces older discrete comparator solutions by integrating four channels into a single small outline package.

Replacement Considerations

Direct replacements include other variants within the MAX6338 family such as MAX6338OUB+ or MAX6338MUB+, provided their specific threshold configurations match the design requirements.
