Electric drive unit for motor vehicle window lifter or windscreen wiper, has power switch combined with control unit in integrated circuit arranged on lead frame

The unit includes an electric motor with a power switch controlled by a control unit based on input signals. The power switch is a semiconductor power switch, e.g. an n-channel MOSFET, and is combined with the control unit in an integrated circuit (11). The integrated circuit is arranged on a lead f...

More Information
Summary:The unit includes an electric motor with a power switch controlled by a control unit based on input signals. The power switch is a semiconductor power switch, e.g. an n-channel MOSFET, and is combined with the control unit in an integrated circuit (11). The integrated circuit is arranged on a lead frame (19) and mechanically and electrically connected to it. The lead frame and integrated circuit are arranged in a gear case (20). Bei einer elektrischen Antriebseinheit für Fahrzeugaggregate, wie Fensterheber, Scheibenwischer o. dgl., mit einem Elektromotor (10), einem im Stromkreis des Elektromotors (10) angeordneten Leistungsschalter und einer Steuereinheit zum Steuern des Leistungsschalters ist zur Reduzierung der Fertigungskosten und Erzielung eines Einbauvolumens der Leistungsschalter als Halbleiter-Leistungsschalter ausgebildet und zusammen mit der Steuereinheit zu einem integrierten Schaltkreis (11) zusammengefaßt. Der integrierte Schaltkreis (11) ist auf einem Stanzgitter (19) angeordnet und mechanisch und elektrisch mit diesem verbunden (Fig. 2).
