AS5047U
14-Bit On-Axis Magnetic Rotary
Position Sensor with Up to 14-Bit
Binary Incremental Pulse Count
General Description
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 a 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.
Ordering Information and Content Guide appear at end of
datasheet.
