MAX6849KASD3

Overview

The MAX6849KASD3 is a low-power battery monitor with hysteresis and an integrated microprocessor reset supervisor. It operates within a supply voltage range of 1.6 V to 5.5 V and is housed in an SOT-23-8 package. The device supports adjustable thresholds for monitoring single-cell lithium-ion or multi-cell alkaline/NiCd/NiMH batteries. It features independent low-battery outputs and an active-low reset output triggered by VCC monitoring.

Feature Summary

• Provides user-adjustable battery monitoring with hysteresis for accurate state detection
• Integrates a dedicated microprocessor supervisor with manual reset capability
• Supports multiple battery chemistries including Li+, alkaline, NiCd, and NiMH

Applications

• Single-cell lithium-ion battery management systems
