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.
FEATUREs
• DAEC ™ Dynamic angle error compensation
• DFS ™ Dynamic filter system
• Magnetic stray field immunity
• Independent output interfaces: SPI, ABI, UVW, PWM
Benefits
• Easy to use – saving costs on DSP
• Higher durability and lower system costs (no
shield needed)
• Versatile choice of the interface
APPLICATIONs
The AS5047U supports BLDC motor commutation for the most challenging industrial applications such as:
• Factory automation
• Building automation
• Robotics
• PMSM (permanent magnet synchronous motor)
• Stepper motor closed loop
• Optical encoder replacement
