Typical Applications (continued)
Table 11. Key Data Flash Parameters for Configuration (continued)
NAME
DEFAULT
UNIT
RECOMMENDED SETTING
Design Energy Scale
1
Set to 10 to convert all power values to cWh or to 1 for mWh. Design Energy is
divided by this value.
Reserve Capacity
0
mAh
Set to desired runtime remaining (in seconds/3600) × typical applied load
between reporting 0% SOC and reaching Terminate Voltage, if needed.
Design Voltage
3800
mV
Set to nominal cell voltage per manufacturer datasheet.
Cycle Count Threshold
900
mAh
Set to 90% of configured Design Capacity
Device Chemistry
0354
hex
Should be configured using TI-supplied Battery Management Studio software.
Default open-circuit voltage and resistance tables are also updated in conjunction
with this step. Do not attempt to manually update reported Device Chemistry as
this does not change all chemistry information! Always update chemistry using
the appropriate software tool (that is, BMS).
Load Mode
1
Set to applicable load model, 0 for constant current or 1 for constant power.
Load Select
1
Set to load profile which most closely matches typical system load.
Qmax Cell 0
1000
mAh
Set to initial configured value for Design Capacity. The gauge will update this
parameter automatically after the optimization cycle and for every regular Qmax
update thereafter.
V at Chg Term
4350
mV
Set to nominal cell voltage for a fully charged cell. The gauge will update this
parameter automatically each time full charge termination is detected.
Terminate Voltage
3000
mV
Set to empty point reference of battery based on system needs. Typical is
between 3000 and 3200 mV.
Ra Max Delta
43
Set to 15% of Cell0 R_a 4 resistance after an optimization cycle is completed.
Charging Voltage
4350
mV
Set based on nominal charge voltage for the battery in normal conditions (25°C,
for example). Used as the reference point for offsetting by Taper Voltage for full
charge termination detection.
Taper Current
100
mA
Set to the nominal taper current of the charger + taper current tolerance to ensure
that the gauge will reliably detect charge termination.
Taper Voltage
100
mV
Sets the voltage window for qualifying full charge termination. Can be set tighter
to avoid or wider to ensure possibility of reporting 100% SOC in outer JEITA
temperature ranges that use derated charging voltage.
Dsg Current Threshold
60
mA
Sets threshold for gauge detecting battery discharge. Should be set lower than
minimal system load expected in the application and higher than Quit Current.
Chg Current Threshold
75
mA
Sets the threshold for detecting battery charge. Can be set higher or lower
depending on typical trickle charge current used. Also should be set higher than
Quit Current.
Quit Current
40
mA
Sets threshold for gauge detecting battery relaxation. Can be set higher or lower
depending on typical standby current and exhibited in the end system.
Avg I Last Run
–299
mA
Current profile used in capacity simulations at onset of discharge or at all times if
Load Select = 0. Should be set to nominal system load. Is automatically updated
by the gauge every cycle.
Avg P Last Run
–1131
mW
Power profile used in capacity simulations at onset of discharge or at all times if
Load Select = 0. Should be set to nominal system power. Is automatically
updated by the gauge every cycle.
Sleep Current
15
mA
Sets the threshold at which the fuel gauge enters SLEEP Mode. Take care in
setting above typical standby currents else entry to SLEEP may be
unintentionally blocked.
Shutdown V
0
mV
If auto-shutdown of fuel gauge is required prior to protect against accidental
discharge to undervoltage condition, set this to desired voltage threshold for
completely powering down the fuel gauge. Recovery occurs when a charger is
connected.
T1 Temp
0
°C
Sets the boundary between charging inhibit/suspend and charging with T1-T2
parameters. Defaults set based on recommended values from JEITA standard.
T2 Temp
10
°C
Sets the boundary between charging with T1-T2 or T2-T3 parameters. Defaults
set based on recommended values from JEITA standard.
T3 Temp
45
°C
Sets the boundary between charging with T2-T3 or T3-T4 parameters. Defaults
set based on recommended values from JEITA standard.
