MAX6427DHUR+

Overview

The MAX6427DHUR+T is a low-power, single-level battery monitor housed in an SOT-23-3 surface-mount package. It operates within a supply voltage range of 1.6 V to 5.5 V and functions across a temperature range of -40°C to +85°C. The device provides a single low-battery output indicator with internal hysteresis to detect battery conditions.

Feature Summary

• Provides a single low-battery output indicator for monitoring power supply status
• Features internal hysteresis to prevent output oscillation during voltage transitions
• Includes a minimum timeout period to ensure supply voltage stabilization before enabling system activity

Applications

• Monitoring single lithium-ion (Li+) cells
• Monitoring multicell alkaline, NiCd, or NiMH power supplies
• Indicating battery conditions such as good, weak, or empty states

Procurement Notes

Verify component authenticity through authorized channels due to discontinuation status. Confirm RoHS compliance and lead-free specifications against current manufacturing data sheets. Validate package integrity and pin configuration prior to integration into design workflows.

Selection Notes

Select this component for applications requiring simple, low-power battery level indication. Ensure the operating voltage range aligns with the target power supply. Consider the single-output limitation compared to dual-level variants if multiple thresholds are required.

Part Context

This part belongs to the MAX6427–MAX6438 family of battery monitors. It shares functional characteristics with other members of the series, differing primarily in threshold voltages and the number of output indicators provided for various battery chemistries.

Replacement Considerations

Consider MAX6428DHUR+T or MAX6429DHUR+T for alternative threshold configurations within the same package. Verify electrical compatibility and pinout alignment before substituting.
