Maxim’s new MAX17047 is a fuel gauge for single-cell Li+ battery packs. Featuring the company’s new ModelGauge m3 algorithm, it is a coulomb-counting fuel gauge that does not suffer from the abrupt corrections that occur with traditional coulomb-counter algorithms.
ModelGauge m3 technology combines the short-term accuracy and linearity of a coulomb counter with the long-term stability of a voltage-based fuel gauge. It cancels offset accumulation error in the coulomb counter, while providing better short-term accuracy than any voltage-only-based fuel gauge. This algorithm makes tiny corrections continually over time, so it does not suffer from the abrupt corrections that normally occur in coulomb-counter algorithms.
The MAX17047 automatically compensates for ageing, temperature and discharge rate. It provides accurate remaining capacity in mAh or SOC % and time-to-empty over a wide range of operating conditions. It uses little power, adapts to changes in the battery over use and time, and warns of abnormal battery conditions. The device provides two methods for reporting the age/health of the battery: reduction in capacity and cycle odometer.
