Abstract

A driver IC (Integrated Circuit) includes a power supply terminal; an output terminal to be coupled to a load element; a connection node on a current path between the power supply terminal and the output terminal; a substrate resistance, having one end coupled to the connection node; an output transistor including a gate, wherein the output transistor is coupled in series with the substrate resistance through the connection node; a resistance, having one end coupled to an other end of the substrate resistance; and a voltage detecting circuit configured to detect a voltage depending on a voltage between the one end of the substrate resistance and the other end of the substrate resistance, and to output an output signal, which is as an output of the voltage detecting circuit, to the gate of the output transistor.
