MAX6338BUB+

Overview

The MAX6338BUB+ is a quad voltage monitor manufactured by Analog Devices Inc. under the Maxim Integrated brand, housed in a 10-pin uMAX package. It monitors four supply voltages without external components, supporting thresholds of 1.8V, 3.3V, 5V, and adjustable settings. The device features active-low open-drain outputs, operates within a +2.5V to +5.5V supply range, and consumes low supply current. It ensures reliable supervision with accuracy guaranteed from -40°C to +85°C.

Feature Summary

• Monitors up to four independent voltage supplies simultaneously
• Factory-programmed or user-adjustable threshold options
• Active-low open-drain output configuration for flexible interfacing

Applications

• Telecommunications systems
• High-end printers
• Desktop and notebook computers
• Data storage equipment
• Networking equipment

Procurement Notes

Verify component authenticity through authorized distributors or official manufacturer channels. Confirm RoHS compliance status and specific lot traceability requirements before procurement. Ensure packaging integrity matches industrial standards for surface-mount assembly processes.

Selection Notes

Select this component when simultaneous monitoring of multiple power rails is required in space-constrained designs. The adjustable comparator option allows adaptation for general-purpose comparison tasks. Verify that the open-drain output logic levels align with downstream digital interface requirements.

Part Context

Part of the MAX6338 family of quad voltage monitors designed for compact electronic applications. The uMAX package provides a small footprint suitable for portable devices. Analog Devices acquired Maxim Integrated, maintaining product lineage and support structures for existing supervisory circuit portfolios.

Replacement Considerations

Direct substitutes include other MAX6338 variants with different threshold configurations such as MAX6338DUB+. Cross-reference pinout compatibility and electrical specifications before substitution.
