LS2:LS0—Learn Stage. See
value controls the influence of the VFG on the mixing
algorithm. At power-up, Learn Stage defaults to 0h, mak-
ing the voltage fuel gauge dominate. Learn Stage then
advances to 7h over the course of two full cell cycles to
make the coulomb counter dominate. Host software can
write the Learn Stage value to 7h to advance to the final
stage at any time. Writing any value between 1h and
6h is ignored. Learn Stage reflects the D5, D6, and D7
bits of the Cycles register. Update the Cycles register
to advance to an intermediate state. For example, set
Cycles = 160% to advance to Learn Stage 5.
The MiscCFG control register enables various other
functions of the device. The MiscCFG register default
values should not be changed unless specifically
required by the application.
register format:
0—Bit must be written 0. Do not write 1.
1—Bit must be written 1. Do not write 0.
X—Don’t Care. Bit may read 0 or 1.
SACFG1:SACFG0—SOC Alert Config. SOC Alerts can
be generated by monitoring any of the SOC registers as
follows. SACFG defaults to 00 at power-up:
0 0 SOC Alerts are generated based on the SOC
0 1 SOC Alerts are generated based on the SOC

MR4:MR0—Mixing Rate. This value sets the strength of
the servo mixing rate after the final mixing state has been
reached (> 2.08 complete cycles). The units are MR0 =
6.25FV, giving a range up to 19.375mA with a standard
0.010I sense resistor. Setting this value to 00000b dis-
ables servo mixing and the IC continues with time-con-
stant mixing indefinitely. The default setting is 18.75FV or
1.875mA with a standard sense resistor.
enBi1—Enable reset on battery-insertion detection. Set
this bit to 1 to force a reset of the fuel gauge whenever a
battery insertion is detected based on AIN pin monitoring.
This bit is written to 1 at power-up.
The FSTAT register is a read-only register that monitors
the status of the ModelGauge algorithm. Do not write
to this register location.
format:
RelDt—Relaxed cell detection. This bit is set to a 1 when-
ever the ModelGauge m3 algorithm detects that the cell
is in a fully relaxed state. This bit is cleared to 0 whenever
a current greater than the Load threshold is detected.
