The AS5304 and AS5306 ICs feature austriamicrosystems’ new line of magnetic encoders for linear and off axis motion sensing applications. The devices provide an easy-to-use, start & play solution for motion control appli- cations as they require no configuration or calibration by the host controller after power up or during operation. The new linear magnetic encoder IC’s can be used in a variety of motion sensing applications found in medical, industrial and consumer products. “The measurement performance and reliability of motion control systems employing traditional optical encoder sensors can be severely impacted by dirt, dust and grime contaminants. Due to the principles of magnetic sen- sing, the AS5304 and AS5306 encoder ICs are immune to these contaminants and can therefore significantly contribute to a higher reliability of motion control applications”, says Matjaz Novak, Marketing Director Industry & Medical at austriamicrosystems. Similar to optical sensors, the AS5304 and AS5306 provide incremental A & B quadrature output signals with 160 steps per magnet pole pair, and an index pulse that is applied once every pole pair. The index pulse toge- ther with the quadrature output signals allow designers to develop applications that track the absolute position once referenced from a known starting position after power up. The AS5304 and AS5306 ICs can achieve resolutions of 25 µm and 15 µm, respectively. In addition to standard linear positioning applications where a magnet strip moves laterally from left to right or vice versa over the IC, the AS5304 and AS5306 encoder ICs also support rotary off axis applications by using a circular ring magnet moun- ted on the outside of a rotating shaft. Rotary off axis encoding solutions can be used in applications where the magnet cannot be placed directly at the end of a rotating shaft due to mechanical constraints. The AS5304 and AS5306 devices are available in a 20-lead 5 × 5 mm TSSOP device and are specified to operate at 5 V over a temperature range of –40 °C to +125 °C. austriamicrosystems AG Schloss Premstätten 8141 Unterpremstätten, Austria Phone: +43 3136 500 5464 Fax: +43 3136 500 5420 www.austriamicrosystems.com [back]
