Abstract

A monolithic controller for the generator unit of a motor vehicle, which is fixedly connected to a cooling body. The cooling body preferably is a thermally conductive ceramic substrate, which is additionally provided with electrically conductive connections, preferably copper structures. In unpackaged form, the monolithic controller is fixedly connected to the substrate.

Claims

1-8. -8. (canceled)

9. A monolithic controller for a generator unit of a motor vehicle, the monolithic controller being fixedly connected to a cooling body, wherein the cooling body is a thermally conductive substrate provided with electrically conductive connections, and the monolithic controller is fixedly connected to the substrate in unpackaged form.

10. The monolithic controller as recited in claim 9, wherein the monolithic controller is connected to the substrate via a rear side.

11. The monolithic controller as recited in claim 9, wherein the electrically conductive connections are one of copper structures or made of conductive paste printing.

12. The monolithic controller as recited in claim 9, wherein the monolithic controller includes bond pads on its front side for electrical contacting.

13. The monolithic controller as recited in claim 9, wherein the monolithic controller is electrically contacted by at least one supplemental component, the supplemental component being an SMD component, the SMD component being fixedly connected to the substrate.

14. The monolithic controller as recited in claim 13, wherein two SMD components are provided on the substrate and the two SMD components are in electrical contact with each other via an electrically conductive connection.

15. The monolithic controller as recited in claim 9, wherein a cross-sectional area of the substrate is larger than a cross-sectional area of the monolithic controller.

16. The monolithic controller as recited in claim 13, wherein the monolithic controller is electrically contacted by one of the SMD components via a bond pad provided on a front side, a lead that is not part of the substrate, and a bond pad provided on the substrate.
