ams: new automotive magnetic sensors

ams extends magnetic position sensors portfolio with AS5270A/B, automotive-grade and ISO26262 safety-compliant dual die integrated circuits.

The new AS5270A and AS5270B system-on-chip (SOC) devices are 0 to 360o rotary magnetic position sensors, that provide contactless high resolution, absolute angle measurements. The AS5270A/B were developed as SEooC (Safety Element out of Context) devices, as defined per the ISO26262 functional safety standard specification.

The new magnetic position sensors provide on-chip full datapath diagnostics, that test the entire device, from the Hall sensor front end, through the DSP engine that converts raw measurements of magnetic field strength into sine and cosine vectors, to the back-end interfaces and pins.

AS5270A/B devices are suitable for many automotive applications including brake and gas pedals, throttle valve and tumble flaps, steering wheel position, chassis ride-height, Exhaust Gas Recirculation (EGR) valves, fuel-level measurement systems, and 2/4 wheel drive switching.
