Abstract
Battery voltage level warning is made according to the output signals of two detecting circuits. A first detecting circuit detects the power supply voltage having lowered to a value somewhat above the lower limit of the operation power supply voltage of an electronic system. The output thereof supplies weak battery warning. The second detecting circuit detects the power supply voltage having lowered to the lower limit level of said operation power-supply voltage. The output thereof prohibits the operation of said electronic system. Thereby, desirable battery-replacement times becomes clarified and the malfunction of said electronic system is prevented.
