Therefore:

1800mAh * 0.002Ω = 3.6mVh

Select:

PFC = 35840 counts or 3.39mVh

SPFC = Z (float)

PROG1, PROG2=HorZ

PROG3 = L

PROG4=HorZ

The initial full battery capacity is 3.39mVh (1695mAh) un-

til the bq2011K “learns” a new capacity with a qualified

discharge from full to EDV.

Nominal Available Charge (NAC):

NAC counts up during charge to a maximum value

of LMD and down during discharge and self dis-

charge to 0. NAC is reset to 0 on initialization and

on the first valid charge following discharge to EDV.

To prevent overstatement of charge during periods

of overcharge, NAC stops incrementing when NAC

= LMD.

Note:

NAC is set to the value in LMD when

PROG4 is pulled low during a reset.
