Description The TEA1103x are fast charge ICs which are able to fast charge NiCd and NiMH batteries. The main fast charge termination for NiCd and NiMH batteries are T/ t and peak voltage detection, both of which are well proven techniques. The TEA1103x automatically switches over from T/t to peak voltage detection if the thermistor fails or is not present. The T/t detection sensitivity is temperature dependent, thus avoiding false charge termination. Three charge states can be distinguished; fast, top-off and trickle. Several LEDs, as well as a buzzer, can be connected to the TEA1103x for indicating battery insertion, charge states, battery full condition and protection mode. Application notes Selection guides Other technical documentation End of Life information The TEA1103x are contained in a 20-pin package and are manufactured in a BiCMOS process, essentially for integrating the complex mix of requirements in a single chip solution. Only a few external low cost components are required in order to build a state of the art charger. The TEA1103x are pin compatible with the TEA1102x, fast charge ICs for LiIon, SLA, NiCd and NiMH batteries.
