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...
