AS5132 360 Step (8.5 bit) Programmable High Speed Magnetic Position Sensor The AS5132 is a contactless magnetic position sensor for General Description accurate angular measurement over a full turn of 360 degrees. It is a system-on-chip, combining integrated Hall elements, analog frontend and digital signal processing in a single device. To measure the angle, only a simple two-pole magnet, rotating over the center of the chip is required. The absolute angle measurement provides instant indication of the magnets angular position with a resolution of 8.5 bit = 360 positions per revolution. This digital data is available as 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. An incremental signal is available as an option. In addition to the angle information, the strength of the magnetic field is also available as a 5-bit code. A one time programmable (OTP) memory is used for permanent zero angle position programming. The magnet does not need to be aligned mechanically. Ordering Information and Content Guide appear at end of datasheet.
