The present invention relates to an actuator device for use in a motor vehicle, comprising an actuator, a control unit for controlling the actuator and a processing unit, which is or can be connected to an external main control device via a control connection in order to transfer actuator setting commands. Furthermore, the processing unit is subordinate to the main control device and is connected to the control unit in order to control the actuator according to the actuator setting commands. The control unit is or can be connected to the main control device via an activation connection and is equipped so as to enable the actuator to be controlled by the processing unit according to activation signals transmitted via the activation connection.

Safety concept for an intelligent actuator

A protective circuit arranged on a Printed Circuit Board (PCB) has two conductor loops. At least one supply voltage track, at least one semiconductor switch and at least one control component are arranged on the PCB. A first terminal of the control component and a first terminal of the semiconductor switch are connected electrically. A first conductor loop of the protective circuit is arranged on the PCB so that it surrounds an electrically conducting connection between the supply voltage track and the semiconductor switch and/or the control component. A second conductor loop is arranged on the PCB so that it surrounds the electrically conducting connection between the first terminal of the control component and the first terminal of the semiconductor switch, and thereby screens the same from the semiconductor switch and at least from those regions of the control component that are also connected to the supply voltage track.
