austriamicrosystems supplies AS5243, the redundant 10-bit magnetic angular position IC, to MEGA-Line RACING ELECTRONICS and Audi R10 for the Le Mans 24 Hours 2008
AS5243 is a system-on-chip combining integrated Hall elements, analog front end and digital signal processing in a single device
The absolute magnetic shaft encoder developed by MEGA-Line RACING ELECTRONIC is based on austriamicrosystems' AS5243 redundant magnetic angular position sensor device which, due to its contactless measurement method, makes the system highly reliable and resistant to adverse environmental conditions such as dust, moisture, vibration or extended temperature conditions. With this sensor the abrasion over the economic lifetime of the gearbox can be monitored. The high performance 10 bit resolution analog output and the extended temperature range up to 150°C (ambient) ideally meets the demands of many safety critical automotive, industrial and robotics applications.
"Our close collaboration with MEGA-Line RACING ELECTRONIC helps us to be successful with innovative solutions on the market," said Bernhard Czar, Director Marketing Automotive at austriamicrosystems.
"austriamicrosystems' wide portfolio of magnetic angular position sensors meet a broad range of customer demands. We look forward to seeing further creative products emerging out of our partnership with MEGA-Line RACING ELECTRONIC."
"We are excited to be working with austriamicrosystems and their new AS5243 absolute angular position sensor technology," said Erwin Gassner, CEO of MEGA-Line RACING ELECTRONIC. "This magnetic encoder technology enables us to get an absolute feedback about the most important gearbox parameter. The barrel position is used to optimize the whole gear change sequence. This sensor has to be absolutely reliable and using the freely programmable AS5243 we do not even need any calibration procedure in the car."
The AS5243 is a contactless magnetic angle position sensor for accurate measurement up to 360° and includes two AS5143 devices in a punched stacked lead frame. It is a system-on-chip combining integrated Hall elements, analog front end and digital signal processing in a single device. The AS5243 provides two separated programmable analog outputs which can be configured in many ways, including user programmable angular range, adjustable output voltage range, voltage or current output, etc.
An internal voltage regulator allows operation of the AS5243 from 3.3V or 5.0V supplies. The AS5243 can detect 1,024 absolute positions over a full turn, 180 and 90 degrees which correspond to a resolution of minimum 0.087 degrees. Additional features include a user programmable zero position and a safety feature that constantly monitors the presence of the magnet. The AS5243 is available in a 7x7mm QFN32 package.
