AS5147 Rotary Position Sensor ICs

The AS5147 from ams OSRAM is a high-resolution rotary position sensor for high speed (up to 28 kRPM) angle measurement over a full 360° range. The position sensor is equipped with a revolutionary integrated dynamic angle error compensation (DAEC™) with almost 0 latency. The robust design of the device suppresses the influence of any homogenous external stray magnetic field. A standard 4-wire SPI serial interface allows a host microcontroller to read 14-bit absolute angle position data from the AS5147 and to program non-volatile settings without a dedicated programmer. Incremental movements are indicated on a set of ABI signals with a maximum resolution of 4096 steps / 1024 pulses per revolution. The product is defined as SEooC (Safety Element out of Context) according to ISO26262, including FMEDA, safety manual, and third party qualification.
