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： 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 power supply switching circuit capable of efficiently supplying a desired voltage among a plurality of voltages to a load. In the case of a P-type semiconductor substrate, N-type MOS transistors are provided between a load and an AC adapter and between the load and a battery, and hence no parasitic diode exists between the load and the AC adapter or the battery, resulting in no current path due to the parasitic diode. Thus, when the AC adapter and the battery are connected to the power supply switching circuit, the N-type MOS transistor is turned off, whereby the current path between the battery and the load is cut off completely and the N-type MOS transistor is turned on. Accordingly, the battery cannot supply a voltage to the load while only the AC adapter can supply a voltage to the load.
