The CCA/DCA will accumulate charging/discharging current, and the counter information will be
shadowed to EEPROM each time the respective counter increments by 0.32C. The memory location
is reserved for the CCA/DCA, and the entire page SHOULD NOT be written to.
Because the user has read/write access to the entire EEPROM array, including the CCA/DCA locations,
the user’s software should never allow a write to memory page 07h if the CCA/DCA are used; otherwise
CCA/ DCA information will be overwritten.
Figure 2 below illustrates the activity of the ICA, CCA, and DCA over a sample charge/discharge cycle
of a battery pack, assuming the DS2437 is configured for the ICA to function and the CCA/DCA to
function and shadow data to EEPROM. To simplify the illustration of the accumulators, they are treated
as analog values, although they are digital counters in the DS2437. Note that when the battery becomes
fully discharged, i.e., the ICA value reaches 0, the CCA and DCA register values are maintained.
