Pressure sensing solution for automotive applications
Summary
The RAA2S425x ICs support all major pressure sensing technologies and feature an analogue front-end (AFE) for enhanced signal conditioning. The RAA2S425x ICs integrate a 16-bit embedded RISC microcontroller that provides digital compensation of offset, sensitivity, temperature drift, and nonlinearity. Digital calibration enables customers to keep assembly costs low since it doesn’t require trimming of sensing element. The company claim that RAA2S425x is an optimal solution for safety and harsh automotive applications with integration of overvoltage and reverse-polarity protection circuitry, ASIL-B compliance according to ISO26262, excellent electromagnetic compatibility, and multiple superior diagnostic features. “The new pressure sensing solution enables our customers to reduce design time with highly accurate, reliable systems meeting tough automotive safety requirements.” The RAA2S425x devices are available today in 4mm x 4mm QFN-24 packages with wettable flanks.
