Ausführungsbeispiel für ein allgemeines Fahrzeugaggregat, weist einen Elektromotor 10, einen im Stromkreis des Elektromotors 10 angeordneten Leistungsschalter und eine Steuereinheit zum Steuern des Leistungsschalters in Abhängigkeit von anliegenden Eingangssignalen auf. Der Leistungsschalter ist als Halbleiter-Leistungsschalter, vorzugsweise als n-Kanal MOS-FET, ausgebildet und zusammen mit der Steuereinheit zu einem integrierten Schaltkreis (IC) 11 zusammengefaßt. Der integrierte Schaltkreis 11 weist insgesamt fünf Anschlüsse 12 - 16 auf, von denen dieExemplary embodiment for a general vehicle assembly has an electric motor 10, a circuit breaker arranged in the circuit of the electric motor 10 and a control unit for controlling the circuit breaker as a function of input signals present. The circuit breaker is designed as a semiconductor circuit breaker, preferably as an n-channel MOS-FET, and combined with the control unit to form an integrated circuit (IC) 11. The integrated circuit 11 has a total of five connections 12-16, of which the
Anschlüsse 12 - 15 auf einen Anschlußstecker 17 gelegt sind und der Anschluß 16 mit der Plus-Kommutatorbürste des als Kommutatormotor ausgebildeten Elektromotors 10 verbunden ist. An den AnschlußStecker 17 ist einerseits die Spannungsversorgung (Klemme 15 und Masse) gelegt und andererseits ein Steuerausgang und ein Diagnoseeingang einer Zentralelektronik 18 des Kraftfahrzeugs angeschlossen. Der integrierte Schaltkreis 11 beinhaltet nur motorrelevante Funktionen, und zwar Aisteuerung des Motors 10 in Abhängigkeit des Eingangssignals MOTOR EIN, Chiptemperatur, Versorgungsspannungslogik, Parklagensignal, Motorbremse, Blockier- und Überlastschutz für den Motor 10, Parklagenerkennung. Wie aus Fig. 2 ersichtlich ist, ist der integrierte Schaltkreis 11 auf einem Stanzgitter 19, auch lead-frame genannt, angeordnet und mechanisch und elektrisch mit diesem verbunden. Die mechanische oder elektrische Verbindung erfolgt dabei durch Löten oder Schweißen der aus dem integrierten Schaltkreis 11 herausragenden Anschlüsse 12 - 16 mit den entsprechenden Metallstegen des Stanzgitters 19. Das Stanzgitter 19 ist in ein Getriebegehäuse 20 eines von der Abtriebswelle des Elektromotors 10 angetriebenen Getriebes eingelegt und an dem aus Kunststoff gefertigen Getriebegehäuse 20 befestigt, z.B. durchConnections 12 - 15 are placed on a connector 17 and the connection 16 is connected to the positive commutator brush of the electric motor 10 designed as a commutator motor. On the one hand, the voltage supply (terminal 15 and ground) is connected to the connector 17 and, on the other hand, a control output and a diagnostic input of central electronics 18 of the motor vehicle are connected. The integrated circuit 11 contains only engine-relevant functions, namely control of the engine 10 in dependence on the input signal ENGINE ON, chip temperature, supply voltage logic, parking position signal, engine brake, blocking and overload protection for the engine 10, parking position detection. As can be seen from FIG. 2, the integrated circuit 11 is arranged on a lead frame 19, also called lead frame, and is mechanically and electrically connected to it. The mechanical or electrical connection is made by soldering or welding the connections 12-16 protruding from the integrated circuit 11 to the corresponding metal webs of the lead frame 19.

Das Stanzgitter 19 ist dabei im Getriebegehäuse 20 so plaziert, daß der integrierte Schaltkreis 11 im unmittelbaren Bereich des Getriebestirnrads liegt. In diesem Getriebestirnrad ist üblicherweise ein Gebermagnet für die Parklagenerkennung des Scheibenwischers eingepreßt, der mit einem in dem integrierten Schaltkreis 11 ausgebildeten Hallsensor zur Erkennung der Parklage und Abschaltung des Motors in der Parklage zusammenwirkt. Weitere Bauteile einer Motorelektronik, z.B. ein Entstörkondensator 21 sowie eine Entstördrossel 22, sind ebenfalls auf dem Stanzgitter 19 befestigt, das die elektrische Verbindung zu den Motoranschlüssen herstellt.

The lead frame 19 is placed in the gear housing 20 so that the integrated circuit 11 is in the immediate area of the gear spur gear. In this gear spur gear, a transmitter magnet for the parking position detection of the windshield wiper is usually pressed in, which cooperates with a Hall sensor formed in the integrated circuit 11 for detecting the parking position and switching off the motor in the parking position. Other components of engine electronics, e.g. a suppression capacitor 21 and a suppression choke 22 are also attached to the lead frame 19, which establishes the electrical connection to the motor connections.
