AS5116 - Highly Reliable and Durable On-Axis Magnetic Rotary Position Sensor for Automotive Electrification
AMS has introduced the AS5116 magnetic rotary position sensor for delivering safe, smart, and green mobility with accurate, contactless angle measurements in demanding automotive applications such as high-speed motors. This is the first device to achieve contactless operation and inherent rejections of stray magnetic fields at a low system cost.
These features deliver a safe, reliable, and durable sensing platform for a new generation of auxiliary motors in vehicles, supporting functions such as electric power steering, actuators within the transmission system, and pumps. The differential sensing architecture outputs reject interference from stray magnetic fields induced by high-voltage cabling and other components in vehicles.
The AS5116 is immune to degradation caused by dust, dirt, grease, moisture, and other contaminants hence is suitable for a new generation of auxiliary motors in the car, supporting functions such as electric power steering, actuators within the transmission system, and pumps. The dedicated safety manual provided with the AS5116 supports customers’ ISO 26262 compliance efforts and is AEC-Q100 Grade 0 qualified for use in automotive applications.
With a low output noise of 2.47mVrms at an operating voltage of 5V, the AS5116 has an inherent non-linearity of just 1° (maximum) over a full 360° turn at rotation speeds up to 30,000rpm. By providing the ability to maximize torque and implement more efficient motor designs AS5116 allows automotive manufacturers to increase fuel efficiency and reduce tailpipe emission. The AS5116 is supplied in an 8-pin SOIC package which has a footprint of 4.9mm x 6.0mm, making it even easier to integrate into automotive system board layouts than earlier ams position sensors.
