Hall encoders enable three dimensional tilt sensor applications

Austriamicrosystems has announced the AS540x product family of three-dimensional Hall encoders. The three-dimensional Hall element is able to provide enhanced resolution with angular or linear output data. This flexibility enables solutions with improved performance for industrial and automotive applications, states the company. The AS540x series was developed in cooperation with Fraunhofer Institute for Integrated Circuits IIS in Germany. The series uses two “pixel-cells” in a differential mode to ensure robustness against all possible external influences like magnetic stray fields. The IC contains an EEPROM, which gives freedom to system designers concerning programming and linearisation of the IC. 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 series is operational over an ambient temperature range from -40 up to 150°C and operates either up to 18V for the automotive or 3V supply voltage for the industry version. The family will be available in a small lead-free TSSOP package.
