Operation description
Once the fast-charge phase has started, if the battery voltage decreases again below V
PRE
,
the charging process is stopped and a fault is signaled. The constant-current fast-charge
phase lasts as long as the battery voltage is lower than V
FLOAT
. When V
BAT
reaches V
FLOAT
,
the charging algorithm switches to constant-voltage (CV) mode.
During the CV mode the battery voltage is regulated to V
FLOAT
and the charging current
starts decreasing. When the charging current reaches the I
END
threshold (I
END
= 10%
I
FAST
), the charging process is stopped and the CHG pin is put in high impedance.
If the fast-charge phase is not terminated within t
FAST
, the charging process is stopped and
a fault is signaled.
The battery temperature is monitored throughout the charging cycle for safety reasons. See
Section 8.3 for more details. Refer to Figure 18 for a simplified flowchart of the charging
process.
