It reports remaining capacity, state-of-charge, and voltage over an I²C bus — no external current-sense resistor needed, because the algorithm learns the battery's impedance from its own discharge curve. ## Package and footprint realities Housed in a 12-VFDFN with exposed pad (12-SON, 2.5x4 mm body).

It updates a model of the battery's internal resistance and capacity, which lets the gauge report state-of-charge accurately even as the cell ages or the temperature changes.
