Description
AveragePower
AP
0x22/0x23
This read-only function returns a signed integer value of average power during battery charging and discharging.
It is negative during discharge and positive during charge. A value of 0 indicates that the battery is not being
discharged. The value is reported in units of mW.
InternalTemperature
INT_TEMP
0x28/0x29
This read-only function returns an unsigned integer value of the measured internal temperature of the device in
0.1-k units measured by the gas gauge.
CycleCount
CC
0x2A/0x2B
This read-only function returns an unsigned integer value of the number of cycles the battery has experienced
a discharge (range 0 to 65535). One cycle occurs when accumulated discharge greater than or equal to CC
threshold.
RelativeStateOfCharge
SOC
0x2C/0x2D
This read-only function returns an unsigned integer value of the predicted remaining battery capacity expressed
as percentage of
FullChargeCapacity()
with a range of 0% to 100%.
StateOfHealth
SOH
0x2E/0x2F
This read-only function returns an unsigned integer value expressed as a percentage of the ratio of predicted
FCC (25C
SoH Load Rate
) over the
DesignCapacity()
. The range is 0x00 to 0x64 for 0% to 100%, respectively.
ChargeVoltage
CV
0x30/0x31
Returns the desired charging voltage in mV to the charger
ChargeCurrent
CC
0x32/0x33
Returns the desired charging current in mA to the charger
DesignCapacity
0x3C/0x3D
In SEALED and UNSEALED access: This command returns the value stored in Design Capacity and is
expressed in mAh. This is intended to be a theoretical or nominal capacity of a new pack, but should have
no bearing on the operation of the gas gauge functionality.
MACSubcmd
0x3E/0x3F
MAC Data block command
MACData
0x40/0x5F
MAC Data block
MACDataSum
0x60
MAC Data block checksum
MACDataLen
0x61

12.1.1 0x00/01 ManufacturerAccess() and ControlStatus()
A write to this register is identical to writing to
MACSubcmd()
. For a description of MAC subcommands, see
.
A read on this register returns the Control bits.
This Control Register is an I
2
C register, and the control bits are read back on register 0x00/0x01. These control
bits are provided for backward compatibility and ease-of-use.
