摘要： Provided are a trimming circuit which does not need a dedicated terminal to which a current for cutting a fuse is input, and also a semiconductor device including the trimming circuit. The trimming circuit includes: an input terminal connected to a pad which is an external terminal of an internal circuit; a fuse provided between a power supply terminal and an output terminal; and a diode provided between the input terminal and the output terminal. The trimming circuit performs trimming by applying, to the pad, such a voltage that the diode is biased in the forward direction.

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.
