General Description
The AS5600 is an easy to program magnetic rotary position sensor with a high-resolution 12-bit analog or PWM output. This contactless system measures the absolute angle of
a diametric magnetized on-axis magnet. This AS5600 is designed for contactless potentiometer applications and its robust design eliminates the influence of any homogenous
external stray magnetic fields. The industry-standard I²C interface supports simple user
programming of non-volatile parameters without requiring a dedicated programmer.
The default range of the output is 0 to 360 degrees. However, full resolution of the
AS5600 can be applied to smaller range by programming a zero angle (start position)
and a maximum angle (stop position). The AS5600 is also equipped with a smart low
power mode feature to automatically reduce the power consumption.
The device is available in a small form factor, compact 8-pin SOIC package.
