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

摘要

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).
