Abstract
An electric motor circuit for controlling an electric motor of a mirror adjustment mechanism includes a switch-off circuit that is provided with a current sensor for measuring the electrical supply current and, depending thereon, generating a voltage. In an embodiment, a current branch is configured to be rendered conductive in response to the generated voltage; an electronic switch is configured to interrupt the supply current as a result of the current branch being rendered conductive. The current branch may be configured to form a first branch of a current mirror which is out of balance and is dimensioned such that the first branch does not carry current under normal operating conditions of the motor, and a second branch is conductive. In an embodiment, upon the occurrence of a supply current that is greater than a predetermined critical level, the first branch is also rendered conductive.
