Rotary 14-bit position sensor for high-speed 360-degree requirements

Available now from Mouser, the ams AS5047P 14-bit magnetic rotary position sensor is designed for high speed (up to 28krpm) angle measurement over a full 360 degree range. The AS5047P is equipped with revolutionary integrated dynamic angle error compensation (DAEC) with almost zero latency. It 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 AS5047P 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 4000 steps/1000 pulses per revolution in decimal mode and 4096 steps/1024 pulses per revolution in binary mode. The resolution of the ABI signal is programmable and can be reduced to 100 steps/25 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. Typical applications include BLDC motor commutation, factory / building automation, robotics, permanent magnet synchronous motors, stepper motors and optical encoder replacement.
