Requirements for design, qualification and production of integrated sensor interface circuits for high quality automotive applications

The product development of integrated sensor interface circuits for automotive applications requires the incorporation of various additional features accounting for the harsh environmental requirements in automotive applications. Unlike in a pure prototype development yield is key to achieve the required automotive quality targets of zero ppm. The paper describes the general automotive requirements like ESD and reverse polarity protection and the design flow from specification until start of production for an industrial product development along with the international standard AEC Q-100 qualification requirement and additional measures during production such as the dynamic part average testing and statistical bin analysis to arrive at zero ppm in the field. The paper includes a real product example of ZMD.
