AS5147P
14-Bit On-Axis Magnetic Rotary
Position Sensor with 12-Bit Binary
Incremental Pulse Count and for
28krpm High Speed Capability
The AS5147P 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 a
revolutionary integrated dynamic angle error compensation
(DAEC™) with almost 0 latency.
The robust design of the device 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 AS5147P 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 4096 steps / 1024 pulses per
revolution. The resolution of ABI signal is programmable to
4096 steps / 1024 pulses per revolution, 2048steps / 512 pulses
per revolution or 1024steps / 256 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 AS5147P supports embedded self-diagnostics including
magnetic field strength too high, magnetic field strength too
low or lost magnet, and other related diagnostic features.
The product is defined as SEooC (Safety Element out of Context)
according ISO26262 including FMEDA, safety manual and third
party qualification.
The AS5147P is available as a single die in a compact 14-pin
TSSOP package.
Ordering Information and Content Guide appear at end of
