<p>A load drive controller for controlling a heat generating member (30) by a switching element (13) includes a temperature detection portion for detecting a physical quantity of a level corresponding to a temperature of the switching element, a protection function portion (15) for outputting an abnormality signal corresponding to an overheated state of the switching element when the physical quantity detected by the temperature detection portion is larger than a value, a control portion (20) for causing the heat generating member to generate heat by driving the switching element via a driving portion (12). Furthermore, the control portion causes a temperature adjustment portion (40,41) to increase the temperature of the heat generating member when the abnormality signal is input from the protection function portion.</p> |
