TEA1102; TEA1102T; TEA1102TS Fast Charge ICs For NiCd, NiMH, SLA And LiIon

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 DT/Dt and peak voltage detection, both of which are well proven techniques. The TEA1102x automatically switches over from DT/Dt to peak voltage detection if the thermistor fails or is not present. The DT/Dt 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.
