Programmable Configuration Settings
Design Capacity
The battery’s rated design capacity or Programmed Full
Count (PFC) is programmed with the PROG
1
–PROG
3
pins as shown in Table 2, and represents the battery’s
full reference.
The correct PFC may be determined by multiplying the
rated battery capacity in mAh by the sense resistor
value:
Battery capacity (mAh)*sense resistor (
) = PFC
(mVh)
Selecting a PFC slightly less than the rated capacity
provides a conservative capacity reference. The bq2052
stores the selected PFC in the PFC register (address =
10h).
DischargeRateandTemperatureCompensation
The discharge rate and temperature compensations are se-
lected using the PROG
4
pin.
power-up or initialization determines which compensation
table the bq2052 uses for the discharge cycle. The following
tables illustrate the calculated efficiency compensation fac-
torsatselecteddischargeratesandtemperatures.

Display Mode
The display mode is selected using the PROG
5
pin. The
three options include a two, four, or five segment display
mode as described in Tables 7,8,and 9.
Initial Capacity Setting
The PFC value is copied to the FNAC register if PROG
6
is programmed high, otherwise FNAC defaults to 0.
FNAC may be written to the desired full capacity to ini-
tialize the pack manually.
Programming Example
Given:
Sense resistor = 0.05m
Number of cells = 5 in series
Capacity = 7000mAh,
Chemistry = LiSO
2
Discharge current range = 250mA to 2A
Voltage drop over sense resistor = 12.5mV to 100mV
Display mode = 5 segment bar graph display
Therefore:
7000mAh*0.05 = 350mVh
Select:
PFC = 26112 counts or 327mVh
PROG
1
= low
PROG
2
= low
PROG
3
= float
PROG
4
= float, high, or low depending on desired com-
pensation factors
PROG
5
= float selects five segment display
PROG
6
= high sets FNAC to PFC
With these selections, the full battery capacity is
327mVh (6540mAh).
