ManufacturerAccess() (0x00); [0x00–0x01]
Description:
This function provides writable command codes to con-
trol the bq2060 during normal operation and pack man-
ufacture. Thefollowing list of commands areavailable.
0x0618 E nable L ow-Power Storage Mode:
Activates
the low-power storage mode. The bq2060 enters the stor-
age mode after a 5–8s delay. The bq2060 accepts other
commands to ManufacturerAccess() during the
before entering low-power storage mode. The L E Ds
must be off before entering the low-power storage mode
as thedisplay stateremains unchanged.
delay
During the delay following the low-power storage com-
mand, a VFC Calibration command may beissued.
The bq2060 clears the ManufacturerAccess() command
within 900ms of acknowledging the Enable Low-Power
Storage command. The VFC Calibration command must
be sent 900–1600ms after SMBus acknowledgment of
the Enable Low-Power Storage command. In this case,
the bq2060 delays entering storage mode until the cali-
bration process completes and the bq2060 stores the
new calibration values in EEPROM.
0x062b SE AL Command:
Instructs the bq2060 to re-
strict access to those functions listed in Table 3.
Note:
The SEAL Command does not change the state of the
SE AL bit in
Pack Configuration
in E E PROM. The
bq2060 completes the seal function and clears
ManufacturerAccess() within 900ms of acknowledging
thecommand.
0x064d
bq2060 to update RM to a percentage of FCC as defined
in
Fast Charge Termination %
. The bq2060 updates RM
and clears ManufacturerAccess() within 900ms of ac-
knowledging thecommand.
C harge Synchronization:
Instructs the
0x0653 E nable VF C Calibration:
Instructs the un-
sealed bq2060 to begin VFC calibration. With this com-
mand the bq2060 deselects the SR
1
and SR
2
inputs and
calibrates for IC offset only. It is best to avoid charge or
discharge currents through the sense resistor during
this calibration process.
0x067e
unsealed bq2060 to begin VFC calibration. With this
Alternate VF C Calibration
:
Instructs the
command the bq2060 does not deselect the SR
1
and SR
2
inputs and calibrates for IC and PCB offset.
During
this procedure no charge or discharge currents
must flow through the sense resistor.
During VFC calibration, the bq2060 disables the LED
display and accepts only the Stop VFC Calibration and
the SE AL Command to ManufacturerAccess(). The
bq2060 disregards all other commands. SMBus
communication should be kept to a minimum during
VFC calibration to reduce the noise level and allow a
moreaccuratecalibration.
Once started, the VFC calibration procedures completes
automatically. When complete, the bq2060 saves the cal-
ibration values in EEPROM. The calibration normally
takes about 8 to 10 minutes. The calibration time is in-
versely proportional to the bq2060 VFC (and PCB) offset
error. The bq2060 caps the calibration time at one hour
in the event of calibrating zero offset error. The VFC cal-
ibration can be done as the last step in a battery pack
test procedure since the calibration can complete auto-
matically after removal from a test setup.
The bq2060 clears ManufacturerAccess() within 900ms
and starts calibration within 3.2s of acknowledging the
command.
0x0660 Stop VF C Calibration:
Instructs the bq2060
to abort a VFC calibration procedure. If aborted, the
bq2060 disables offset correction. The bq2060 stops cali-
bration within 20ms of acknowledging thecommand.
0x0606
bq2060 to connect the SMBus to the EEPROM I
2
C bus.
The bq2060 applies power to the EEPROM within 900ms
of acknowledging the command. After issuing the pro-
gram EEPROM command, the bq2060 monitoring func-
tions are disabled until the I
2
C bus is disconnected. The
bq2060 disconnects the I
2
C bus when it detects that the
Battery Address 0x16 is sent over the SMBus. The Bat-
tery Address 0x16 to disconnect the I
2
C bus should not
besent until 10ms after thelast writetotheEEPROM.

E xample:
The following sequence of actions is an exam-
ple of how to use the ManufacturerAccess() commands
in an efficient manner to take a battery pack that has
completed all testing and calibration except for VFC cal-
ibration and to make it ready for shipment in the
SEALED stateand in low-power storagemode:
1.
Complete testing and calibration with desired final
values stored in EEPROM. This process includes
setting SEAL bit in Pack Configuration. Sending a
reset command to the bq2060 during test ensures
that RDM values correspond to the final EEPROM
values
2.
If RemainingCapacity() initial value must be
non-zero, the desired value may be written to
