APPLICATION INFORMATION
current termination
During the CV mode, the charge cycle is terminated when the charging current is under the programmed
terminated level or when the total charge timer (TCTR) times out. The terminated current level can be
programmed to 10%, 20%, 30%, 40%, or 50% of the charging current at CC mode.
temperature monitoring
The TWL2214CA device monitors the battery temperature throughout the charge cycle. The input for ADC
reference voltage is generated by a negative temperature coefficient (NTC) thermistor. The TWL2214CA device
compares the ADC input reference voltage to the programmed threshold voltages to determine if charging is
allowed. Three required thresholds are:
VBOTRH+ Voltage for over-temperature cutoff; charging is suspended.
VBOTRH
–
Voltage to resume charging function for over-temperature cutoff.
VBOTRL
Voltage for low-temperature cutoff; charging is suspended.

Figure 21. Temperature Monitoring
NOTE: The power-up default values are zero for these three thresholds. If the user opts not to use the temperature monitoring function during
the charge cycle, the TS terminal of the device must be tied to GND to avoid an error signal.
