General Description
The MagnTek rotary position sensor MT6701
is an IC based on Hall sensing technology. The
chip senses the Z-Axis component of the
rotating magnet in the X-Y plane and delivers
two sinusoidal output signals to the DSP
which indicating the angle (α) between the
sensor and the magnetic field direction.
The incremental ABZ output mode is available
in this sensor series, making the chip suitable
to replace various optical encoders. The
maximum resolution is 1024 pulses/4096 steps
per revolution in binary mode.
A standard I2C or SSI interface allows a host
microcontroller to read the 14-bit absolute
a n g l e p o s i t i o n d a t a f r om MT 6 7 0 1 . T h e
absolute angle position is also provided as
P W M o u t p u t o r l i n e a r a n a l o g s i g n a l
proportional to VDD from a 12-bit DAC.
Additionally, the PUSH output indicates the
fast air-gap changes between the MT6701 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 MT6701.
