14-bit magnetic rotary encoder IC for automotive applications

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.”
