ams, a company specializing in sensors and analog ICs, announced that it has expanded its portfolio of functional safety compliant sensors.

The newly launched sensor series is the first magnetic position sensor offered by ams in a System-in-Package (SiP) format. SiP is a space-saving package that can reduce system costs and enables the use of sensor devices even in environments where PCB-based packaging is prohibited.

The new AS5170 and AS5171 sensors were developed for use in SEooC (Safety Element out of Context) products, as defined by the ISO26262 functional safety standard. With ams’ magnetic position sensors, the AS517x components provide full data path diagnostics, enabling automotive system OEMs to achieve ISO26262 system-level performance.



The AS517x series sensors, certified as 'AEC-Q100 Grade 0', enable precise measurements and cover safety functions such as vehicle chassis height, gear shifter, electronic power steering (EPS), exhaust gas recirculation (EGR), brake pedal, as well as throttle position detection.

Power protection features have also been improved. The Supply and Output pins are protected against overvoltages of up to +20V. The power pin is protected down to -20V in reverse polarity.

Marcel Urban, Head of Product Management and Marketing for position sensors at ams, said, “The highly stringent automotive functional safety compliance process requires the use of components that provide full clarity and traceability regarding performance and diagnostic results. The new AS517x is ams’ first series of magnetic position sensors to provide this level of safety functionality, offering automotive OEMs a much more complete set of features than previous products used to comply with the ISO 26262 standard.”
