AS5047U 14-Bit On-Axis Magnetic Rotary Position Sensor with Up to 14-Bit Binary Incremental Pulse Count Datasheet
■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.
■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.
●Benefits
■Easy to use – saving costs on DSP
■Higher durability and lower system costs (no shield needed)
■Versatile choice of the interface
●Features
■DAEC ™ Dynamic angle error compensation
■DFS ™ Dynamic filter system
■Magnetic stray field immunity
■Independent output interfaces: SPI, ABI, UVW, PWM
