14-bit magnetic rotary encoder IC to convert rotational motion into electric signal

austriamicrosystems' new 14-bit magnetic rotary encoder IC AS1563 is designed for measuring rotational angle measurement in automotives from controls like throttle control pedals.
With wire control going big way in automotives, semiconductor ICs such as these aid in replacing clumsy mechanical throttle and other such control in automotives with wire control systems.


Operating from a supply voltage of 5 volts, AS5163 is rugged enough to meet automotive electronics requirements.
The protection features available are,
I. +27 Volt over-voltage protection
II. -18 Volt reverse polarity protection at supply pins.
III. Intelligent short circuit monitoring function

Andreas Pfingstl, Product Manager Automotive Encoders at austriamicrosystems said, "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 single wire pin can be configured either as a 14-bit digital, 12-bit PWM or ratiometric analog output and also the IC can be customized for any system specific angle range. The programming of the desired angle range is achieved by setting a start and end position of the rotational movement.

Operating ambient temperature range: -40°C to 150°C
Package: TSSOP 14 package
