PSI5 Automotive Safety Digital Accelerometer
NXLS95xxxx and NXLS96xxxx are the recommended devices for new designs starting Q1-2026. FXLS90xxxx and FXLS93xxxx will continue to be supported in production until inventory depletion.
The FXLS93 family is the latest generation of airbag crash sensors from NXP. The devices are designed using NXP proprietary UMEMS sensing technology combined together with a signal conditioning ASIC in a QFN 4 x 4 x 1.45 mm package.
The devices feature a user PSI5 interface. They can measure acceleration in single or dual independent axis configuration from +/-15.5 g to +/-500 g. The embedded DSP provides fully programmable digital high and low pass filtering.
The FXLS93 family is fully AEC-Q100 qualified up to 125 °C operating temperature and is compliant with the AK LV 27 requirements. The package has wettable flanks for solder join inspection. FXLS93 products have been developed following ISO26262 2018 edition and can be used in up to ASIL D system.
