Abstract: An information processing device, method and computer program storage device that cooperate to handle different user interface situations differently. An exemplary device detects an external object as being in a touch state when and external object is in contact with a detection surface, and an adjacent state when the external object is within a predetermined distance from said detection surface but not in contact with said detection surface. A processor, when operating in a first mode, processes the touch state differently than the adjacent state. Also, the processor when operating in a second mode, processes said adjacent state as if it was the touch state.

Before all terminals of a battery protection circuit are each connected to batteries, even when a logical circuit malfunctions by an operation of a parasitic bipolar transistor formed by P-wells due to a connection order in which the batteries are connected, the logical circuit is reset by an operation of a parasitic bipolar transistor formed by the P-wells.

Abstract: An overcharge detecting comparator (121) detects an overcharged state of a battery (101), and an overcurrent detecting comparator (120) detects an overcurrent state of the battery (101). In response to output signals from those comparators, a control circuit (210) performs on/off control of each of a switch (102) and a protection circuit (50). In response to an output signal from the control circuit (210), the protection circuit (50) is turned on, to thereby connect a resistor (125) to a path connecting a VSS terminal and an overcurrent detecting terminal, and is turned off, to thereby disconnect the resistor (125) from the path. As a result, even when the battery is in the overcurrent state, current consumption can be reduced.
