Arousal of Li-ion batteries: Pre-charge circuit: Fast charge and termination: Temperature monitoring: TWL2213 is monitoring the temperature of lithium ion battery all the time during the charging period, and it uses NTC thermal resistor to produce ADC input reference voltage. TWL2213 will compare ADC reference voltage with programmable threshold voltage, then it will decide to stop the process of charging or over heat cutting.
