  • Publication number: 20080224664
    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.

  • Patent number: 7420903
    Abstract: Disclosed is electronic equipment enjoying improved ease of use, and a highlighting method and a program to be implemented or installed in the electronic equipment. For example, a user performs manipulations so as to reproduce a content up to the middle of the content, and then turns off a power supply. When the user turns on the power supply next, a playback selection menu screen image is displayed and “Playback from the middle thereof” is highlighted. Consequently, when the user wants to reproduce the content from the middle of the content, the user need not worry about whether to reproduce the content from the beginning or the middle thereof. The user should merely finalize the highlighted item. This would prove user-friendly and helpful. When the electronic equipment is used outdoors or the like, the number of manipulations to be performed on the equipment is smaller than the number of manipulations conventionally performed.

  • Publication number: 20080203971
    Abstract: An object of the present invention is to provide a battery state monitoring circuit and a battery device which are capable of normally operating when a charger (301) is connected to an opposite polarity in error, and then correctly connected. In the case where the charger (301) is connected to the opposite polarity in error and then correctly connected, a logic circuit (305) does not output a power-down signal that powers down the respective circuits to the respective circuits by the aid of a power-down preventing circuit (110). As a result, the battery device normally operates without falling into the power-down state.

  • Publication number: 20080164563
    Abstract: A thin film capacitor including a substrate, a capacitor portion having an upper conductor, a lower conductor, and a dielectric thin film, and a resin protective layer for protecting the capacitor portion. A barrier layer is interposed between the capacitor portion and the resin protective layer. The barrier layer includes a crystalline dielectric barrier layer formed in contact with the capacitor portion and having the same composition system as the dielectric thin film, and an amorphous inorganic barrier layer formed on the surface of the crystalline dielectric barrier layer and composed of silicon nitride having non-conductivity. The inorganic barrier layer prevents deterioration in the properties of the dielectric thin film by blocking diffusion of the constituent elements of the inorganic barrier layer toward the capacitor portion.

  • Publication number: 20080157719
    Abstract: Provided are a semiconductor device and a rechargeable power supply unit which are capable of accurately detecting an overcharge state of a battery even in a case where the battery is charged with a sine wave charger. In a case where a 1/2 cycle of a charging voltage of the sine wave charger is shorter than a delay time for cancellation of an overdischarge state, when it is detected that a voltage of the battery in the overdischarge state exceeds an overdischarge detection voltage and becomes equal to or higher than an overcharge detection voltage, a delay circuit sets the delay time for cancellation of the overdischarge state to 0 seconds.
