AS5047P
14-bit On-Axis Magnetic Rotary
Position Sensor with 12-Bit Decimal &
Binary Incremental Pulse Count for
28krpm high speed capability
General Description
Figure 1:
Added Value of using the AS5047P
The AS5047P is a high-resolution rotary position sensor for high
speed (up to 28krpm) 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 AS5047P 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 4000 steps / 1000 pulses per
revolution in decimal mode and 4096 steps / 1024 pulses per
revolution in binary mode. The resolution of the ABI signal is
programmable and can be reduced to 100 steps per revolution,
or 25 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 AS5047P is available as a single die in a compact 14-pin
TSSOP package.
