General Description
AS5047D
14-bit On-Axis Magnetic Rotary
Position Sensor with 11-bit Decimal &
Binary Incremental Pulse Count
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.
Incremental movements are indicated on a set of ABI signals
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 resolution of the ABI signal is
programmable and can be reduced to 32 steps per revolution,
or 8 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
The AS5047D is available as a single die in a compact 14-pin
TSSOP package.
