AS5601
12-bit Programmable Contactless
Encoder
General Description
The AS5601 is an easy-to-program magnetic rotary position
sensor with incremental quadrature (A/B) and 12-bit digital
outputs. Additionally, the PUSH output indicates fast airgap
changes between the AS5601 and magnet which can be used
to implement a contactless pushbutton function in which the
knob can be pressed to move the magnet toward the AS5601.
This AS5601 is designed for contactless encoder applications,
and its robust design rejects the influence of any homogenous
external stray magnetic fields.
Based on planar Hall sensor technology, this device measures
the orthogonal component of the flux density (Bz) from an
external magnet.
The industry-standard I²C interface supports user
programming of non-volatile parameters in the AS5601 without
requiring a dedicated programmer.
The AS5601 also provides a smart low-power mode which
automatically reduces power consumption
