AS5132
360 Step (8.5 bit) Programmable High Speed Magnetic Rotary Encoder
1 General Description
The AS5132 is a contactless magnetic rotary encoder for 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
magnet’s 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 software programmable (OTP) zero position simplifies assembly
as the zero position. The magnet does not need to be mechanically
aligned.
