1 / 51 page  ams Datasheet Page 1 [v1-00] 2018-Oct-30 Document Feedback AS5047U 14-Bit On-Axis Magnetic Rotary Position Sensor with Up to 14-Bit Binary Incremental Pulse Count 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. Ordering Information and Content Guide appear at end of datasheet. Key Benefits & Features The benefits and features of this device are listed below: Figure 1: Added Value of Using the AS5047U Benefits Features • Easy to use – saving costs on DSP • DAEC ™ Dynamic angle error compensation • DFS ™ Dynamic filter system • Higher durability and lower system costs (no shield needed) • Magnetic stray field immunity • Versatile choice of the interface • Independent output interfaces: SPI, ABI, UVW, PWM General Description |
