MAX6338LUB

Overview

The MAX6338LUB+ is a quad voltage monitor from the Maxim Integrated family, housed in a 10-pin µMAX package. It monitors four supply voltages without external components. Factory-trimmed thresholds include +5.0V, +3.3V, +2.5V, and adjustable settings. It features low 25µA supply current, four independent open-drain active-low outputs, and operates within a +2.5V to +5.5V supply range. The device is guaranteed for operation from -40°C to +85°C.

Feature Summary

• Monitors up to four power supplies simultaneously using factory-programmed or user-adjustable threshold options.
• Provides four independent open-drain active-low reset outputs for flexible system integration.
• Operates with minimal supply current consumption of 25µA, optimizing power efficiency.
• Requires no external components for basic voltage monitoring functionality.

Applications

• Telecommunications equipment
• Desktop and notebook computers
• Data storage systems

Procurement Notes

Verify the specific suffix 'LUB' against official Analog Devices documentation to confirm exact threshold configurations. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability may vary. Ensure the 10-pin µMAX package matches your PCB footprint requirements before ordering.

Selection Notes

Select this component when simultaneous monitoring of four distinct voltage rails is required in space-constrained designs. The adjustable comparator option allows customization for non-standard voltage levels. Consider the open-drain output structure for compatibility with various logic families.

Part Context

Part of the MAX6338 series of quad voltage monitors designed for compact surface-mount applications. The µMAX package provides a small form factor suitable for portable and high-density electronics. Manufactured by Analog Devices Inc., formerly Maxim Integrated.

Replacement Considerations

Check for direct substitutes within the MAX6338 family with different suffixes (e.g., DUB, JUB) that match required voltage thresholds. Verify pinout compatibility if considering alternative quad supervisors from other manufacturers.
