as follows:

VOVM is between 0 and 4080mV.
Charging Current
ChargingCurrent() values are either broadcast to a
Level 2 Smart Battery Charger or read from the bq2060
by a Level 3 Smart Battery Charger. The bq2060 sets
the value of ChargingCurrent(), depending on the
chargerequirements and chargeconditions of thepack.
When fast charge is allowed, the bq2060 sets
ChargingCurrent() to the rate programmed in
F ast
Charging Current
EE 0x1a-0x1b.
When fast charge terminates, the bq2060 sets
ChargingCurrent() to zero and then to the
Maintenance
Charging Current
EE 0x1c-0x1d when the termination
condition ceases.
When Voltage() is less than E DV0, the bq2060 sets
ChargingCurrent() to
Pre-charge Current
EE 0x1e-0x1f.
Typically this rate is larger than the maintenance rate
to charge a deeply depleted pack up to the point where it
may befast charged.
Fast Charging Current
,
Maintenance Charging Current

and
Pre-ChargeCurrent
arestored in mA.
Charge Suspension
During charge, the bq2060 compares the current to the
ChargingCurrent() plus the value IOIM. If the pack is
charged at a current above the ChargingCurrent() plus
IOIM, the bq2060 sets ChargingCurrent() set to zero to
stop charging. IOIM is programmed in the EEPROM
value,
Overcurrent Margin
, encoded as:

Overcurrent Margin
EE 0x49 may be used to program
IOIM values of 0 to4080mA in 16mA steps.
The desired temperature threshold for charge suspen-
sion, MAXTE MP, may be programmed between 45

FULLY_CHARGED Bit Clear Threshold

BatteryStatus() when RelativeStateOfCharge() reaches
the value,
F ully Charged Clear %
E E 0x4c.
F ully
Charged Clear %
is an 8-bit value and is stored as a 2’s
complement of percent.
Fast Charge Termination Percentage
The bq2060 sets RM to a percentage of FCC on charge
termination if the CSYNC bit is set in the Pack Configu-
ration register. The percentage of FCC is stored in
Fast
Charge Termination %
in EE 0x4b. The value is stored
in 2’s complement of percent.

Cycle Count Threshold
mAh that must be removed from the battery to incre-
ment CycleCount(). Cycle Count Threshold is a 16-bit
