资源简介: AS5132
360 Step (8.5 bit) Programmable High
Speed Magnetic Position Sensor
The AS5132 is a contactless magnetic position sensor 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 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
