VCELL Register
Battery voltage is measured at the CELL pin input with
respect to GND over a 0 to 5.00V range for the
MAX17040 and 0 to 10.00V for the MAX17041 with res-
olutions of 1.25mV and 2.50mV, respectively. The A/D
calculates the average cell voltage for a period of
125ms after IC POR and then for a period of 500ms for
every cycle afterwards. The result is placed in the
VCELL register at the end of each conversion period.
Figure 3 shows the VCELL register format.
SOC Register
The SOC register is a read-only register that displays
the state of charge of the cell as calculated by the
ModelGauge algorithm. The result is displayed as a
percentage of the cell ’s full capacity. This register
MSB—ADDRESS 02h
automatically adapts to variation in battery size since
the MAX17040/MAX17041 naturally recognize relative
SOC. Units of % can be directly determined by observ-
ing only the high byte of the SOC register. The low byte
provides additional resolution in units 1/256%. The
reported SOC also includes residual capacity, which
might not be available to the actual application because
of early termination voltage requirements. When SOC()
= 0, typical applications have no remaining capacity.
The first update occurs within 250ms after POR of the
IC. Subsequent updates occur at variable intervals
depending on application conditions. ModelGauge cal-
culations outside the register are clamped at minimum
and maximum register limits. Figure 4 shows the SOC
register format.
