MAX6338AUB

Overview

The MAX6338AUB+ is a quad voltage monitor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It monitors four independent supply voltages without requiring external components, utilizing factory-trimmed threshold settings for optimized performance. The device features four open-drain active-low outputs and operates within a +2.5V to +5.5V supply range. It guarantees accuracy from -40°C to +85°C and is housed in a compact 10-pin µMAX package.

Feature Summary

• Monitors up to four distinct supply voltages simultaneously
• Factory-programmed threshold options eliminate external component requirements
• Provides four independent open-drain active-low reset outputs

Applications

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

Procurement Notes

Verify the specific suffix designation against official datasheets to confirm exact threshold configurations. Ensure compatibility with required operating temperatures and supply voltage ranges before integration. Confirm RoHS compliance status and packaging type matches project specifications.

Selection Notes

Select this component when monitoring multiple power rails is necessary without adding passive components. Consider the available factory-trimmed thresholds such as +5.0V, +3.3V, or adjustable inputs. Evaluate the low supply current consumption and small footprint for space-constrained designs.

Part Context
