We present a dual-sensor package technology allowing integration of two separate sensor chips in just one device, which has the same dimensions as a regular single-chip sensor. By offering built-in redundancy, the dual-sensor package supports the achievement of the highest safety level, ASIL-D in safety-related automotive applications.
The chips are placed on top and bottom of the package leadframe, so that the lateral position of the sensing elements coincides. This mounting technique ensures a maximum relative measurement accuracy of the two sensor chips. Furthermore, the small footprint of the dual-sensor package enables the implementation of redundant sensors in applications with limited space, thus saving precious space and cost.
