App note: Battery fuel gauge IC (LC709203F) for 1-Cell Lithium-ion (Li+)

Lithium-ion fuel gauge IC from ON Semiconductors. Link here (PDF)

The LC709203F is an IC that measures the remaining power level of 1-cell lithium-ion (Li+) batteries used for portable
equipment etc.
This product reduces fuel gauge errors with a unique correction technology during measurement of battery temperature and
voltage.
This technology has inherently high precision without the need for an external sense.
