The MAX17050 remains in production, however, for new projects, we recommend ModelGauge m5 MAX17055 fuel gauge.
The MAX17047/MAX17050 incorporate the Maxim ModelGauge™ m3 algorithm that combines the excellent short-term accuracy and linearity of a coulomb counter with the excellent long-term stability of a voltage-based fuel gauge, along with temperature compensation to provide industry-leading fuel-gauge accuracy. ModelGauge m3 cancels offset accumulation error in the coulomb counter while providing better short-term accuracy than any purely voltage-based fuel gauge. Additionally, the ModelGauge m3 algorithm does not suffer from abrupt corrections that normally occur in coulomb-counter algorithms since tiny continual corrections are distributed over time.
The device automatically compensates for aging, temperature, and discharge rate and provides accurate state of charge (SOC) in mAh or %, as well as time-to-empty over a wide range of operating conditions. The device provides two methods for reporting the age of the battery: reduction in capacity and cycle odometer.
The device provides precision measurements of current, voltage, and temperature. Temperature of the battery pack is measured using an external thermistor supported by ratiometric measurements on an auxiliary input. A 2-wire (I2C) interface provides access to data and control registers. The MAX17047 is available in a lead(Pb)-free, 3mm x 3mm, 10-pin TDFN package. The MAX17050 is available in a 0.4mm pitch 9-bump WLP package.
