SMBus Protocol:
Read Block
Output:
Block data—data that reflects EEPROM program-
ming as assigned by the manufacturer with maxi-
mum length of 7 characters (7+length byte).
Pack Status and Pack Configuration (0x2f);
[0x2f]
This function returns the Pack Status and Pack Config-
uration registers. The Pack Status register contains a
number of status bits relating to bq2060 operation. The
Pack Status register is the least significant byte of the
word.
OCE
The OCE bit indicates that offset cancellation is en-
abled. The bq2060 sets this bit after VFC offset calibra-
tion is complete.
0
Offset calibration is not enabled
1
Offset calibration is enabled
E DV2
The EDV2 bit indicates that Voltage() is less than the
EDV2 threshold.
0
Voltage() > EDV2 threshold
1
Voltage()
≤
EDV2 threshold
E INT
The EINT bits indicate that the VFC has detected a
chargeor dischargepulse.
0
Nocharge/dischargeactivity detected
1
Charge/dischargeactivity detected.
VDQ
The VDQ bit indicates if the present discharge cycle is
valid for an FCC update.
0
Dischargecycleis not valid
1
Dischargecycleis valid
COK
The COK bit indicates the status of the CFC pin of the
bq2060.
0
1
CFC pin is low
CFC pin is high
DOK
The DOK bit indicates the status of the DFC pin of the
bq2060.
0
DFC pin is low
1
DFC pin is high
CVOV
The CVOV bit indicates that a secondary Li-Ion protec-
tion limit has been exceeded. It is set if any individual
cell exceeds the programmed high voltage limit, if the
pack voltage exceeds the overvoltage threshold, or if an
over temperature condition occurs. The bit is not latched
and merely reflects thepresent overvoltagestatus.
0
Nosecondary protection limits exceeded
1
A secondary protection limit exceeded
CVUV
The CVUV bit indicates if any individual cell falls below
the programmed low-voltage limit. The bit applies to
lithium batteries only. The bit is not latched and merely
reflects thepresent undervoltagestatus.
0
All series cells areabovethelow-voltagelimit
1
A series cell is below thelow voltagelimit
The Pack Configuration register reflects how the bq2060
is configured as defined by the value programmed in
Pack Configuration
in EE 0x3f.
VCELL4–VCELL1 (0x3c–0x3f); [0x3c–0x3f]
These functions return the calculated voltages in mV at
theVCELL
4
through VCELL
1
inputs.
EEPROM
General
The bq2060 accesses the external EEPROM during a
full reset and when storing historical data. During an
EEPROM access, the V
OUT
pin becomes active and the
bq2060 uses the ESCL and ESDA pins to communicate
with the EEPROM. The EEPROM stores basic configu-
ration information for use by the bq2060. The EEPROM
must be programmed correctly for proper bq2060 opera-
tion.
Memory Map
Table 10 shows the memory map for the EEPROM. It
also contains example data for a 10 series NiMH and a
3s3p Li-Ion battery pack with a 0.05
senseresistor.
