Example: Selecting a PFC Value
Given:
Sense resistor = 0.1
Number of cells = 6
Capacity = 2200mAh,NiCd battery
Current range = 50mA to 2A
Absolute display mode
Serial port only
Self-discharge =
C
Voltage drop over sense resistor = 5mV to 200mV
Therefore:
2200mAh*0.1
= 220mVh
Select:
PFC = 33792 counts or 211mVh

The initial full battery capacity is 211mVh
(2110mAh) until the bq2010 “l(fā)earns” a new capac-
ity with a qualified discharge from full to EDV1.
