... 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 ...

... The main function of the control logic is to support the communication between several blocks. It also controls the charge method, initialization and battery full detection. The block diagram of the TEA1102x is illustrated in Fig.1. Conditioning charge method and initializations At system switch-on battery insertion, the control logic sets the initialization mode in the timer block ...

... V for SLA for Lilon. When charging, the standby mode (LiIon and SLA) can only be entered after a certain period of time depending on time-out. The same applies for charging NiCd or NiMH batteries. To support full test of the TEA1102x at application, the standby mode is also entered when V < fill-up or top-off respectively ...
