AS5270A/B series magnetic position sensors are designed by ams with increased safety and diagnostic capabilities to help achieve the highest in ISO26262 ASIL system safety-level compliance. Developed as SEooC devices, the sensors are suited for automotive applications including brake and gas pedals, throttle valve and tumble flaps, steering wheel position, chassis ride-height, EGR valves, fuel-level measurement systems, and 2/4 wheel drive switching. The 0 - 360° rotary sensors provide contactless high resolution, absolute angle measurements.
Operating off 5 V and immune to magnetic stray fields, the sensors provide on-chip full datapath diagnostics that test the entire device, including Hall sensor front end, DSP engine, and back-end interfaces and pins. AEC-Q100 Grade 0 qualified, the stacked and aligned dual-die devices come in MLF-16 SMT packages.
The AS5270A model provides analog output. The AS5270B provides either programmable digital SENT or PWM output, and offers programmable settings for SENT and PWM interface protocols. Both devices support programmable angular range limit clamps, digital filtering and output linearization. The AS5270A/B magnetic position sensors are available for $3.98 each/1,000.
