Fuel Gauge Operation
The operation overview diagram in Figure 9 illustrates the
fuel gauge operation of the ISL6295. The ISL6295
incorporates four 32-bit accumulators and four 32-bit
elapsed time counters. The Charge Current Accumulator
(CCA) and Discharge Current Accumulator (DCA)
accumulate a measure of charge and discharge currents for
the capacity calculation and cycle count. The Charge Time
Counter (CTC) and Discharge Time Counter (DTC) are
intended to maintain the total charge time and discharge
time for the self-discharge, average charge, and discharge
currents over an extended period of time.

Delta_Capacity_Count = CCA - DCA
Delta_Time_Count = CTC + DTC
Capacity Calculation
Gross_Capacity (mAh) = (Delta_Capacity_Count *
130μAs) / (1000 * 3600)
Adjusted_Capacity = Gross_Capacity - SelfDischarge_Loss
SelfDischarge_Loss (mAh) = SelfDischarge_LookupTable
[ItCtrl/EtCtrl] * ((Delta_Time_Count * 0.5)/3600)

1. 130μAs is the Accumulator LSB based upon 20m
sensor
resistor and 15-bit resolution;
2. The length of CCA, DCA, CTC, and DTC are 32-bit long;
3. CCA, DCA, CTC, and DTC will be updated every 0.5 second;
