Austriamicrosystems has expanded its magnetic rotary encoder range with the AS5245, a fail-safe magnetic rotary encoder IC specifically designed for safety critical automotive applications such as pedals, transmission and steering wheels.

Based on a stacked-die technology, the AS5245 provides phase matching capabilities. No additional temperature compensation, calibration or shielding against external magnetic stray fields is needed, said the supplier.

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 bit.

Features include user-specific zero programming, chip-ID and diagnostic functions for the correct positioning of the magnet.

An internal voltage regulator allows the AS5245 to operate at either 3.3V or 5V supply within a wide ambient temperature range of up to 150°C. The AS5245 is available in a lead-free QFN 32 package.
