1 / 40 page  ams Datasheet Page 1 [v1-07] 2016-Apr-27 Document Feedback AS5047D 14-Bit On-Axis Magnetic Rotary Position Sensor with 11-Bit Decimal and Binary Incremental Pulse Count The AS5047D 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 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 AS5047D 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 2000 steps / 500 pulses per revolution in decimal mode and 2048 steps / 512 pulses per revolution in binary mode. The resolution of the ABI signal is programmable and can be reduced to 32 steps per revolution, or 8 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 AS5047D is available as a single die in a compact 14-pin TSSOP package. Ordering Information and Content Guide appear at end of datasheet. Key Benefits & Features The benefits and features of AS5047D, 14-Bit On-Axis Magnetic Rotary Position Sensor with 11-Bit Decimal and Binary Incremental Pulse Count are listed below: Figure 1: Added Value of Using the AS5047D Benefits Features • Easy to use – saving costs on DSP • DAEC™ Dynamic angle error compensation • Good resolution for motor and position control • 14-bit core resolution • Simple optical encoder replacement • ABI programmable decimal and binary pulse-count: 500, 400, 300, 200, 100, 50, 25, 8, 512, 256 ppr • No programmer needed (via SPI command) • Zero position, configuration programmable General Description |
