Abstract
An electrical circuit has a power source line from a battery. The power source line is divided into a primary side and a secondary side by a device, such as, for example, a diode. A high current load circuit is connected to the primary side and a lower current device, such as, for example, a display-related circuit and a capacitor are connected to the secondary side. The display-related circuit continues to receive adequate power when the battery voltage drops due to operation of the high current load circuit. In addition, a voltage detector is connected to the secondary side, where the voltage fluctuates less than on the primary side. The voltage detector controls operation of the high current load circuit. As a result, the high current load circuit can be efficiently driven.
