ModelGauge m3 Fuel Gauge
ModelGauge Algorithm
Output Registers
The following registers hold the output results from the
ModelGauge m3 algorithm.
SOC
MIX
Register (0Dh)
The SOC
MIX
register holds the calculated present state
of charge of the cell before any empty compensation
adjustments are performed. The register value is stored
as a percentage with a resolution of 0.0039% per LSb.
If an 8-bit state-of-charge value is desired, the host can
discard the lower byte and use only the upper byte of
the register with a resolution of 1.0%.

RemCap
MIX
Register (0Fh)
The RemCap
MIX
register holds the calculated remain-
ing capacity of the cell before any empty compensation
adjustments are performed. The value is stored in terms
of FVh and must be divided by the application sense-
resistor value to determine remaining capacity in mAh.

SOC
REP
Register (06h)
SOC
REP
is a filtered version of the SOC
AV
register that
prevents large jumps in the reported value caused by
changes in the application such as abrupt changes in
load current. The register value is stored as a percent-
age with a resolution of 0.0039% per LSb. If an 8-bit SOC
value is desired, the host can discard the lower byte and
use only the upper byte of the register with a resolution
of 1.0%.
