Rotary Encoder IC Addresses Automotive Needs

Austriamicrosystems has introduced the AS5245, a magnetic rotary encoder IC designed to address automotive requirements such as reliability, accuracy and safety. Based on Austriamicrosystems' stacked-die technology, the AS5245 provides best phase matching capabilities.

No additional temperature compensation, calibration or shielding against external magnetic stray fields is needed. The digital angle data of the AS5245 is provided as a simple serial interface or as a PWM signal.

In addition, an incremental quadrature output mode with an improved interpolation algorithm can be enabled and permanently programmed with a resolution of 10 or 12 bit. An internal voltage regulator allows the AS5245 to operate at 3.3 or 5V supply within a wide ambient temperature range of up to 150C. The AS5245 is available in a lead-free QFN 32 package.
