Abstract
PURPOSE:To generate the best set voltage by an apparatus itself which uses a battery, such as a clock, etc., by selecting a battery life detecting resistance by a signal from a frequency dividing circuit of an electronic clock. CONSTITUTION:When a point A is made low and an output of a frequency dividing circuit is provided to terminals (a), (b) and (c), eight kinds of states are generated by operation of an input gate 1, and these eight kinds of states are stored in a storage device provided on the outside. On the other hand, when the eight states are provided to a resistance splitting circuit 2, the transmission gate is turned on and off, and eight kinds of voltage are generated by eight kinds of resistance states. Subsequently, the best voltage is selected, and after that, each state of the terminals (a), (b) and (c) which have generated said voltage is generated by terminals C1, C2 and C3 by cutting a bonding wire, and when the point A is set to a high state, the battery life detecting circuit is operated by the set state of the terminals C1, C2 and C3, irrespective of the state of the terminals (a), (b) and (c).
