austriamicrosystems expanded its extensive magnetic rotary encoder portfolio with the AS5245, a fail-safe magnetic rotary encoder IC capable of addressing stringent automotive requirements like reliability, accuracy and safety.

Based on the company’s stacked-die technology, the device provides advanced phase matching capabilities. No additional temperature compensation, calibration or shielding against external magnetic stray fields is needed. To give system designers more flexibility during evaluation, the digital angle data of the AS5245 is provided either 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 bits.

Standard features include user-specific zero programming, chip-ID and diagnostic functions for the correct positioning of the magnet. An internal voltage regulator allows the device to operate at either 3,3 V or 5 V supply within a wide ambient temperature range of up to 150°C.
