An EMC-robust high voltage system-on-chip

Abstract

This paper describes an intelligent actuator and sensor interface for a bridge-type sensor for automotive applications, requiring high voltage capability, robustness for electrostatic discharge (ESD) and electromagnetic compatibility (EMC) and having to operate in a wide temperature range. With respect to EMC, both low emission as well as low sensitivity to external disturbances is required. In this paper the main functional blocks of the sensor are described with emphasis on the special circuits to fulfil the automotive requirements.
