摘要： In order to provide an overheat protection circuit having a small mounting area, the overheat protection circuit includes: a resistor bridge circuit which includes: a plurality of resistors each having a temperature coefficient; an input terminal; and an output terminal; and a comparator circuit connected to the output terminal and the input terminal of the resistor bridge circuit. Parts are each provided in the vicinity of one of the plurality of resistors each having the temperature coefficient, and the comparator circuit outputs an overheat detection signal when a temperature of one of the parts is equal to or higher than an overheat detection temperature. With this structure, a large number of parts can be protected from overheating by a minimum number of overheat protection circuits. Therefore, a circuit scale becomes smaller, and hence a cost for overheat protection becomes lower.

摘要： Provided is a battery protection circuit and a battery device which may be manufactured at lower cost. 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. For this reason, a charge/discharge path of the batteries is not interrupted due to the connection order. Accordingly, no limitation is placed on the connection order.

摘要： A charge and discharge control circuit which accommodates pulsed charge and pulsed discharge and can control charge and discharge of a secondary battery with safety, and a rechargeable power supply device having the same built therein are provided. The charge and discharge control circuit includes a delay time switching circuit for shortening a delay time of overcharge detection after charge inhibition is canceled. When overcharge is detected after the charge inhibition is canceled, the charge is inhibited in a delay time which is shorter than a normal delay time of the overcharge detection.

摘要： Provided are a battery protection IC adaptable to any number of batteries connected in series without increasing a breakdown voltage thereof, and a battery device including the battery protection IC mounted thereon. A charge control signal input terminal and a discharge control signal input terminal of one battery protection IC are provided with a clamp circuit (121), and hence an output driver (112) of another battery protection IC connected to those terminals is not applied with a voltage equal to or higher than a breakdown voltage. Accordingly, the breakdown voltage of the battery protection IC is not required to be high.
