摘要： Provided are a charge/discharge control circuit having a self-test function, which can dispense with a complicated test device, and a battery device. The battery device includes the charge/discharge control circuits each including a pull-up/pull-down circuit provided at a terminal to which a secondary battery is to be connected. When a self-test start signal is input so as to enter a self-test state, a self-test control circuit controls the pull-up/pull-down circuit, to thereby perform a test on a voltage detection circuit provided at the terminal to which the secondary battery is to be connected. When the self-test is finished, a self-test start signal is output to a next-stage charge/discharge control circuit, to thereby perform a test sequentially on the voltage detection circuits of the cascade-connected charge/discharge control circuits.

摘要： 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.

摘要： 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.
