Overview
The MAX6432BHUS+T is a low-power, dual-level battery monitor from the Maxim Integrated MAX6427–MAX6438 family. It provides two independent low-battery output indicators with internal hysteresis to detect three battery states: good, weak, or empty. Designed for single lithium-ion cells or multi-cell alkaline/NiCd/NiMH supplies, it asserts outputs when voltage drops below specified thresholds and deasserts when rising above high thresholds. The device operates within a temperature range of -40°C to +85°C and is housed in a compact SOT143-4 package.
Feature Summary
- Dual-level monitoring capability for precise battery state indication
- Internal hysteresis prevents output oscillation near threshold voltages
- Supports multiple battery chemistries including Li+, alkaline, NiCd, and NiMH
Applications
- Single lithium-ion cell monitoring systems
- Multi-cell alkaline power supply management
- NiCd/NiMH battery pack status indication
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix '+T' indicates tape-and-reel packaging if required for automated assembly. Check current product status as some variants in this family may be obsolete; ensure availability aligns with long-term production needs before finalizing procurement decisions.
Selection Notes
Select this component when dual-threshold detection is required for accurate battery life estimation. Ensure the operating voltage range matches the target battery chemistry. Consider the SOT143-4 package size constraints for PCB layout. Verify that the internal hysteresis values meet the system's noise immunity requirements without compromising sensitivity.
Part Context
Part of the MAX6427–MAX6438 series of low-power battery monitors. This family offers single or dual-level options for various battery types. The MAX6432 variant specifically provides dual outputs for enhanced monitoring granularity compared to single-output counterparts like the MAX6427.
FAQ
What battery chemistries does the MAX6432BHUS+T support?
It supports single lithium-ion (Li+) cells and multi-cell alkaline, NiCd, or NiMH power supplies.
How many battery conditions can the device indicate?
It indicates three conditions: battery is good, battery is weak, or battery is empty.
