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 ModelGaugeK to track the battery relative
state-of-charge (SOC) continuously over a widely varying
charge/discharge conditions. The ModelGauge algo-
rithm 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 I
The ICs are available in a tiny 0.9mm x 1.7mm, 8-bump
wafer-level package (WLP) or a 2mm x 2mm, 8-pin TDFN
package.

Detailed Description ModelGauge Theory of Operation The MAX17058/MAX17059 ICs simulate the internal, non- linear dynamics of a Li+ battery to determine its state of charge (SOC). The sophisticated battery model consid- ers impedance and the slow rate of chemical reactions ...
