... An application note (AN95085) is available describing the versatility of the TEA1104; TEA1104T. An external power current source charges the batteries via an electronic switch which is controlled by the TEA1104. The TEA1104 monitors the battery voltage. Fully charged batteries are detected when the battery voltage peaks. In fact, a voltage drop of 0.25% with respect to the top value is detected. Fast charging is initiated at ‘ ...

... IC for NiCd and NiMH chargers Output drivers Several output drive possibilities are supported by the TEA1104, to limit the fast charge current and to indicate the mode that the charge is in. In mains isolated systems, output drive current is available for a bipolar or MOS switching device. Moreover, current regulators can be driven (see Fig ...
