austriamicrosystems Introduces 14-bit Magnetic Rotary Encoder IC with Best-in-Class Device Protection for the Toughest Automotive Applications

AS5163 is austriamicrosystems' first automotive magnetic encoder IC to meet the toughest automotive requirements for overvoltage and reverse polarity protection

Unterpremstaetten, Austria (May 19, 2009) - austriamicrosystems (SIX: AMS), a leading global designer and manufacturer of high performance analog ICs for automotive, communication, industry and medical applications, today introduced AS5163, the first magnetic rotary encoder IC specifically designed to satisfy stringent automotive requirements in angle sensing applications where robust IC protection is essential.

austriamicrosystems' newest automotive magnetic encoder IC incorporates both +27 Volt overvoltage protection and -18 Volt reverse polarity protection at its output. AS5163 also features an intelligent short circuit monitoring function which forces the IC to power down under short circuit condition, thus protecting the device from being damaged, and allows the encoder to resume reliable operation when normal condition is restored.

The AS5163 offers up to 14-bit resolution on a single-wire output. The output can be configured either as a 14-bit digital, 12-bit PWM or analog. Moreover, the device can be programmed to measure a full rotational angle over 360° or a user-defined fraction of it. This makes AS5163 ideally suited in automotive applications such as throttle and flap systems or gas-pedal units.

Due to austriamicrosystems' patented differential mode sensor interface, the AS5263 is substantially insensitive to the unwanted external magnetic fields. This reduces the need for magnetic shielding of the device in environments where external magnetic fields can cause an unreliable operation. The encoder IC is operational over an extended temperature range from -40°C to 150°C.

"In the automotive industry with its constantly growing demands with regard to device protection and system reliability, our AS5163 is perfectly positioned to meet these challenges", comments Andreas Pfingstl, Product Manager Automotive Encoders at austriamicrosystems. "When developing this device, we put special emphasis on the ease of use and cost efficiency for the user. The AS5163 offers a single-wire interface and, together with its robust protection features, allows system designers to meet their performance and reliability requirements, while optimizing system cost."

The AS5163 is available in a small TSSOP 14 package and operates at 5V supply voltage. For product specific information, to download data sheets or to request free samples from austriamicrosystems' online shop ICdirect, please visit www.austriamicrosystems.com/rotary-encoder/AS5163 .

austriamicrosystems will showcase the AS5163 at the Sensor & Test in Nürnberg May 26 to 28, 2009, booth# 12-460 and also at the Sensors Expo in Chicago June 8 to 10, 2009, booth #521. Get more information at www.austriamicrosystems.com/Events
