General Description

The AS5147 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 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. The resolution of the ABI signal is programmable to 2048 steps / 512 pulses per revolution or 1024 steps / 256 pulses per revolution. The AS5147 has also a programmable UVW output and supports embedded self-diagnostics features.

Magnets cannot be ordered at ams directly. Please find a list of recommended magnet suppliers.

This product suits for the following applications:

  • Electric power steering (EPS)
  • Transmission (gearbox, actuator)
  • Pump
  • Brake (actuator)
  • Starter and alternator
