Product Details
The MAX17058/MAX17059 ICs are tiny fuel gauges for lithium-ion (Li+) batteries in handheld and portable equipment. The MAX17058 operates with a single Li+ cell and the MAX17059 with two Li+ cells in series.
The ICs use the sophisticated Li+ battery-modeling algorithm ModelGauge™ to track the battery relative state-of-charge (SOC) continuously over a widely varying charge/discharge conditions. The ModelGauge algorithm eliminates current-sense resistor and battery-learn cycles required by other fuel gauges. Temperature compensation is implemented using the system micro-controller.
On battery insertion, the ICs debounce initial voltage measurements to improve the initial SOC estimate, allowing them to be located on system side. SOC and voltage information is accessed using the I2C interface. The ICs are available in a tiny 0.9mm x 1.7mm, 8-bump wafer-level package (WLP) or a 2mm × 2mm, 8-pin TDFN package.
