Overview
The MAX6431MRUS+T is a low-power, dual-level battery monitor from the MAX6427–MAX6438 family. It provides two independent low-battery output indicators to signal three distinct battery states: good, weak, and empty. The device features internal hysteresis to prevent output chatter during voltage transitions. It is designed for monitoring single lithium-ion cells or multicell alkaline, NiCd, and NiMH power supplies. The component operates within a temperature range of -40°C to +85°C and is available in a compact SOT-143 package.
Feature Summary
- Dual low-battery output indicators for precise state detection
- Internal hysteresis prevents output oscillation
- Supports multiple battery chemistries including Li+, alkaline, NiCd, and NiMH
Applications
- Single lithium-ion cell monitoring
- Multicell alkaline power supply supervision
- NiCd/NiMH battery pack management
Procurement Notes
Verify the specific suffix against the manufacturer's official documentation to confirm pinout compatibility and electrical characteristics. Ensure the ordering part number matches the required package variant and temperature grade. Cross-reference the datasheet revision date to validate parameter accuracy before integration into design specifications.
Selection Notes
Select this component when dual-threshold monitoring is required for systems needing distinct low-power and shutdown signals. It is suitable for applications where internal hysteresis reduces external component count. Consider the operating temperature range and package constraints relative to the target enclosure design.
Part Context
This device belongs to the MAX6427–MAX6438 series of battery monitors. The series offers configurable single or dual output options. The MAX6431 specifically provides dual outputs for enhanced battery status granularity compared to single-output variants in the same family.
Replacement Considerations
Check MAX6430, MAX6432, MAX6436, MAX6437, and MAX6438 for functional equivalents within the same series. Verify package compatibility and threshold voltage specifications before substitution.
