Measurement Calibration
ADC
To describe how the bq2060 calculates reported battery
and individual cell voltages, the following abbreviations
and designations areused:
V CE L L
1–4
= voltages at the input pins of the
bq2060
VCELL1–4 = reported cell voltages
Vnl–4 = voltages at the different series nodes in the
battery
Voltage() = reported battery voltage
V
sr
= voltageacross thesenseresistor
The reported voltages measurements, Voltage() and
VCELL1–4, may be calibrated by adjusting five 8- or
16-bit registers in E E PROM:
ADC
Offset
in E E 0x62,
ADC
Voltage Gain
in EE 0x66–0x67,
Cell 2 Calibration
Factor
in EE 0x63,
Cell 3 Calibration Factor
in EE 0x64,
and
Cell 4 Calibration Factor in
EE 0x65.
The bq2060 first computes the node voltages Vnl, Vn2,
Vn3, and Vn4. The node voltages are inputs to the volt-
age dividers to the VCELL
1
through VCELL
4
input pins
of the bq2060. The bq2060 computes node voltages to
calculate the five reported voltages by the bq2060: Volt-
age(), VCELL1, VCELL2, VCELL3, and VCELL4.
An
ADC
Voltage Gain
factor of 20,000 is the nominal
value when using the recommended cell-voltage division
ratios of 16:1 on the VCELL
4
and VCELL
3
inputs and
8:1 on the VCELL
2
and VCELL
1
inputs. The bq2060
subtracts the voltage across the sense resistor from the
measurements so that the reported voltages reflect the
cell-stack voltages only.

Note:
With LCC1-LCC0 = 00,
Cell 4 Calibration

= 0.
ADC Offset
adjusts the ADC offset for voltage and cur-
rent measurements.
ADC
Offset is
a signed 8-bit value
that cancels offset present in the circuit with no poten-
tial or current flow.
ADC
Offset is
typically set between
-10 and 10.
