ABSTRACT:
A battery assembly is provided for holding a battery and for supplying power to an integrated circuit. When the battery is removed from the battery assembly, the battery assembly provides a LOW level signal to either the high voltage input (Vdd) of the integrated circuit or the reset port of the integrated circuit. The battery assembly includes a battery holder, a negative electrode attached to the battery holder and electrically connected to the a negative power line related to the integrated circuit, and a positive electrode also attached to the battery holder and connected to a positive power line to provide power to the integrated circuit. The positive and negative electrodes are disposed such that the battery may be held between the positive and negative electrodes, with positive and negative terminals of the battery in electrical contact with the positive and negative electrodes. The negative electrode includes an electrically conductive extension. Furthermore, the battery assembly includes a shifting element for shifting the extension into a contact position to be in electrical contact with a reset port of the integrated circuit, or to be in electrical contact with the positive electrode, when the battery is removed from the holder. Thus, a LOW level signal from the negative electrode is provided to a reset port of the integrated circuit or the positive voltage (Vdd) port of the integrated circuit. Thus the integrated circuit is properly reset.
