as5132 rotary position sensor

AS5132: 8.5-bit Rotary Position Sensor With Digital Angle (Interface), ABI, UVW (up to 6 pole pairs) and PWM Output

The AS5132 is a contactless magnetic rotary position sensor for accurate angular measurement over a full turn of 360 degrees. The absolute angle measurement provides instant indication of the magnet’s angular position with a resolution of 8.5 bit = 360 positions per revolution via a serial output over the interface and as a pulse width modulated (PWM) signal. An additional U,V,W output can be used for a block commutation for a brushless DC motor. To improve the torque over speed, a pre-commutation is possible.
