MAX6431EHUS-T

Battery Management Overview

The MAX6431EHUS-T is a dual-level, factory-trimmed battery monitor IC designed for multi-chemistry applications. It features two active-low open-drain low-battery outputs (LBOH and LBOL) to indicate battery depletion levels. The device operates within a wide supply voltage range and is housed in a compact SOT143-4 package. It provides reliable monitoring for portable electronic devices requiring precise battery status indication without complex circuitry.

Battery Management Feature Summary

• Dual-level monitoring with separate high and low battery output thresholds
• Factory-trimmed accuracy eliminates external calibration requirements
• Active-low open-drain outputs compatible with various logic families
• Designed for multi-chemistry battery types including Li-ion and NiMH

Battery Management Applications

• Portable consumer electronics battery management
• Mobile phone power management systems
• Digital camera battery status indication
• Medical device power monitoring

Battery Management Procurement Notes

Verify the exact suffix designation (+T vs -T) as it may indicate packaging or compliance variations. Confirm the manufacturer source is authorized Analog Devices or Maxim Integrated. Check for RoHS compliance markings on the component marking. Ensure the SOT143-4 package type matches your PCB footprint requirements before ordering.

Battery Management Selection Notes

Select this component when dual-threshold battery monitoring is required for portable devices. Consider the fixed threshold voltages provided by the factory trimming. Evaluate the SOT143-4 package size against available board space. Verify compatibility with the specific battery chemistry being monitored for accurate threshold performance.

Battery Management Part Context

This part belongs to the MAX6431 family of battery monitors from Maxim Integrated. It serves as a dedicated solution for indicating battery depletion in portable electronics. The EHUS variant specifies the temperature grade and package type. It complements other power management ICs in complete system designs.

Battery Management Replacement Considerations

Check for MAX6431CHUS-T as a potential alternative within the same family. Verify pinout compatibility and threshold voltage specifications before substitution. Ensure the replacement part supports the same battery chemistries and operating conditions.
