AS5047U

14-Bit On-Axis Magnetic Rotary

Position Sensor with Up to 14-Bit

Binary Incremental Pulse Count

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.

General Description

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.
