MAX17332X22+T

Overview

The MAX17332X22+T is a highly integrated single-cell lithium-ion or lithium-polymer battery management system. It combines an AccuCharge programmable charger, a ModelGauge m5 fuel gauge, and protection logic in one solution. The device features a coulomb counter for precise capacity tracking and multi-channel ADCs for monitoring voltage, current, and temperature. It operates within a supply range of 4V to 30V and supports I2C communication for data access.

Feature Summary

• Integrates a standalone charger with intelligent fuel gauge estimation using the ModelGauge m5 algorithm.
• Includes comprehensive safety protection mechanisms against over-voltage, under-voltage, over-current, and over-temperature conditions.
• Provides high-precision coulomb counting and real-time monitoring of battery parameters via a standard interface.

Applications

• Compact portable consumer electronics
• Handheld medical devices
• IoT sensor nodes
