APPLICATION INFORMATION
maximum time out
The TWL2214CA device provides three timers for maximal time allowed for charging. The time is programmable
through I
2
C interface.

Precharge timer
0
–
136 min
4 min
During the precharge cycle, if the timer expires before the precharging activity is
complete, a BATT_ERR flag is set in the status register, and the charge is
terminated.
CCTR

274 min
8 min
During the CC mode cycle, if the timer expires before the CC activity is complete,
a BATT_ERR flag is set in the status register, and the charge is terminated.
TCTR

total charge timer
0
–
15 hr
1 hr
Total charge time is defined as the total charge time of CC mode and CV mode.
TCTR time-out occurs only in the CV mode. If the timer expires before, the charge
is complete.
