Measures battery voltage, current, and temperature, and integrates current over time to track state-of-charge (SoC). I2C interface for host MCU access to battery status, remaining capacity, and health parameters.","working_principle":"A sense resistor in the battery path measures current. The Coulomb counter integrates this current over time to track charge added\/removed. Battery voltage measurement provides open-circuit voltage (OCV) for SoC correlation. The IC combines Coulomb counting with OCV-based correction for accurate fuel gauge across temperature and aging.","pin_description":"
