A compact MCM implementation of an embedded system for automotive applications

In this paper a multichip module system for automotive applications is described. The use of microsystems in automotive industry allows size reduction of electronic units and also a reduction in its cost. The presented microsystem is based on a IMS (Isolated Metal Substrate) substrate, which has been used for integration of analog signal processing stages, complex logic circuits, sensors and even power transistors. The functionality of the microsystem is the control of a power window motor with antipinch feature. The system architecture is based on a single microcontroller and a multipurpose ASIC. The trapping detection strategy is based on current sensing and signal processing.
