STMicroelectronics introduces integrated angular rate sensors for ADAS

What happened

STMicroelectronics is introducing its first automotive safety combination sensors aimed at mass-market applications, integrated angular rate sensors, following the integration of NXP's sensors division. The devices combine multi-axis accelerometers and gyroscopes (angular rate sensors) in a single package, are ISO 26262-compliant and provide full internal diagnostics, offering OEMs and Tier-1 suppliers a unified platform for active and passive safety systems, with applications including crash protection, rollover detection, airbag deployment, vehicle stability controls and radar beam stabilisation. The specific part numbers are: NCS1012BAEP (z-axis (yaw) angular rate sensor and xy low g acceleration sensor), NCS1012CAEP (x-axis (roll) angular rate sensor and yz low g acceleration sensor), NCS1012EAEP (x-axis (roll) angular rate sensor and xy medium g acceleration sensor), and NCS10135AEP (z-axis (yaw) angular rate sensor and xyz low g acceleration sensor). The integrated angular rate sensors have a range of ±125 dps, ±250 dps or ±350 dps, operate over the automotive temperature range (−40°C to +105°C), and feature an integrated low-pass filter with 3dB frequency options of 12.5Hz to 400Hz plus an optional single-pole high-pass filter with fast startup. Regarding availability, the four new sensors are in production, in 24-pin QFN 6mm x 6mm x 1.90mm packages with wettable flanks.
