MAX6429MTUR+T

Overview

The MAX6429MTUR+T is a low-power, single-level battery monitor housed in an SOT-23 package. It operates within a supply voltage range of 1 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 prevent output chatter during voltage transitions. A minimum timeout period ensures supply voltages stabilize before system activity is enabled.

Feature Summary

• Provides a single low-battery output indicator for monitoring power supply conditions
• Features internal hysteresis to ensure stable output states during voltage fluctuations
• Includes a minimum timeout period to allow supply voltages to stabilize before enabling system activity

Applications

• Monitoring single lithium-ion cells
• Monitoring multicell alkaline power supplies
• Monitoring NiCd or NiMH power supplies

Procurement Notes

Verify the specific suffix 'MTUR' against official Analog Devices documentation to confirm exact tape-and-reel packaging specifications and temperature grade. Confirm RoHS compliance status through current manufacturer declarations. Ensure the component source is authorized to avoid counterfeit parts, as availability may be limited.

Selection Notes

Select this component when a single low-battery threshold detection is required for portable electronics. It is suitable for applications needing simple power management without complex dual-level logic. Verify that the operating voltage range aligns with the target battery chemistry and that the SOT-23 package fits the design constraints.

Part Context

This part belongs to the MAX6427–MAX6438 family of low-power battery monitors from Maxim Integrated. These devices are designed to indicate three battery conditions: good, weak, or empty. The MAX6429 variant specifically offers a single low-battery output, distinguishing it from dual-output models in the same series.

Replacement Considerations

Compatible substitutes within the same family include MAX6427, MAX6428, MAX6430, MAX6431, MAX6432, MAX6433, MAX6434, MAX6435, MAX6436, MAX6437, and MAX6438. Verify pinout compatibility and threshold voltage requirements before substitution.
