描述

The AS5047U 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 at higher rotational speed. For increased signal quality at lower rotational speed, the dynamic filter system (DFS ™) reduces transition noise.
The robust design of the device suppresses the influence of any
homogenous external stray magnetic field. A standard 4-wire
SPI serial interface with a CRC protection allows a host
microcontroller to read 14-bit absolute angle position data
from the AS5047U 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 16989 steps / 4096 pulses per
revolution.
Brushless DC (BLDC) motors are controlled through a standard
UVW commutation interface with a programmable number of
pole pairs from 1 to 7. The absolute angle position is also
provided as PWM-encoded output signal.
AS5047U are single die sensors and are available in a TSSOP14
Package.

With two decades of magnetic sensor system know-how, we have broad experience in selecting the most suitable magnets. ams experts recommend the following magnet suppliers.
