MAGNETIC POSITION SENSORS
The AS5047D is a high-resolution rotary position sensor for fast absolute angle measurement over a full 360-degree range. This new position sensor is equipped with revolutionary integrated dynamic angle error compensation (DAEC™) with almost 0 latency and offers a robust design that 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 AS5047D and to program non-volatile settings without a dedicated programmer. The resolution of the incremental ABI interface is programmable with a maximum resolution of 2000 steps / 500 pulses per revolution in decimal mode and 2048 steps / 512 pules per revolution in binary mode.
The AS5047D is ideally suited to support BLDC motor commutation for the most challenging industrial applications such as building automation, factory automation, PMSM (permanent magnet synchronous motor), robotics, and stepper motors closed loop in as well optical encoder replacement.
