OSRAM AS5047P-TS_EK_AB

The AS5047P is a high-resolution rotary position sensor for high-speed (up to 28krpm) angle measurement over a full 360-degree range. This new position sensor features a revolutionary integrated Dynamic Angle Error Compensation (DAEC) with near-zero latency and provides a robust design that suppresses the effects of any homogeneous external stray magnetic fields. A standard 4-wire SPI serial interface allows a master microcontroller to read 14-bit absolute angle position data from the AS5047P and to program non-volatile settings without a dedicated programmer. Incremental motion is indicated via 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 signals is programmable down to 100 steps or 25 pulses per revolution. Brushless DC (BLDC) motors are controlled via a standard UVW commutation interface with the number of pole pairs programmable from 1 to 7. The absolute angle position is also provided as a PWM-encoded output signal. The AS5047P is available as a single-chip solution in a compact 14-pin TSSOP package.
