Hall sensor opererer i tre dimensioner
austriamicrosystems introducerer '3D HallinOne' magnetisk enkoder familier, der er udviklet i samarbejde med Fraunhofer institut (in english).
austriamicrosystems announces the AS540x product family of 3-dimensional Hall encoders. The new three-dimensional Hall element is able to provide absolute and highest resolution with angular or linear output data. This new flexibility enables new solutions with improved performance for industrial and automotive applications. The AS540x series was developed in cooperation with Fraunhofer Institute for Integrated Circuits IIS in Germany - license holder of the HallinOne technology.
austriamicrosystems AS540x series uses two 'pixel-cells' in a differential mode to guarantee robustness against all possible external influences like magnetic stray fields. In addition, the IC contains an EEPROM , which gives maximum freedom to system designers concerning programming and linearization of the IC.
- The strength of this technology is the true 3D measurement of magnetic field components. Accurately calibrated lateral and vertical Hall sensors are used to increase the overall performance. The differential approach by using two 3D pixels cells also extends the absolute linear position measurement range up to 40mm. If we are talking about challenging automotive and industrial position sensing requirements in harsh environments, the AS540x family is currently the best way to go, says Marcel Urban, Product Manager Magnetic Encoder at austriamicrosystems.
- The HallinOne technology has proven its maturity in high volume ASIC-based applications. The standard products commonly developed with austriamicrosystems will open this technology for robust and innovative position sensing applications to those customers who are not willing to develop their own ASIC, says Josef Sauerer, head of analog and mixed signal IC Design at Fraunhofer IIS.
By using a simple two pole magnet, the absolute position information of the magnet is directly accessible over a SPI interface for module or as a PWM interface for remote applications. The AS540x series is operational over an ambient temperature range from -40°C up to 150°C and operates either up to 18V for the automotive or 3V supply voltage for the industry version. The AS540x family will be available in a small lead-free TSSOP package.
austriamicrosystems is developing a portfolio of 3D Hall products for automotive and industrial applications. The first 3D Hall product AS5401 for industrial applications will be launched in Q1 / 2011, samples of the automotive version with implemented high voltage diagnostic features will be available soon.
