Information as of 2000-08-19
TEA1102; TEA1102T; TEA1102TS; Fast charge ICs for NiCd, NiMH, SLA and LiIon
The TEA1102x are fast charge ICs which are able fast charge NiCd and NiMH, SLA and Lilon 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 TEA1102x 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.
Charging Lilon and SLA batteries is completely different. When the batteries reach their maximum voltage (adjustable), the TEA1102x
switches over from current regulation to voltage regulation. After a defined time period, which is dependent on battery capacity and charge
current, charge is terminated. Due to small self discharge rates of Lilon and SLA batteries, trickle charge can be omitted.
Several LEDs, as well as a buzzer, can be connected to the TEA1102x for indicating battery insertion, charge states, battery full condition
and protection mode.
The TEA1102x 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.
