Description
The ATS605LSG provides a single IC solution to rotational
position sensing applications with a ferrous gear target.
The SG package incorporates a rare earth pellet for ease of
manufacturing, consistent performance over temperature, and
enhanced reliability.
Three Hall elements are incorporated to create two independent
differential channels. These channels are processed by the
IC which contains a sophisticated digital circuit designed
to eliminate the detrimental effects of magnet and system
offsets. Hall differential signals are used to produce a highly
accurate speed output and, if desired, provide information on
the direction of rotation.
Advanced calibration techniques are used to optimize signal
offset and amplitude. This calibration, combined with the
digital tracking of the signal, results in accurate switch-points
over air gap, speed, and temperature. The open-drain outputs
provide voltage output signals which mirror the sensed target’s
shape, with a phase separation between the two channels
proportionate to the size of the target teeth vs. the Hall element
spacing. This sensor IC system is optimized for a variety of
applications requiring dual phase gear speed and position signal
information or simultaneous high-resolution gear speed and
direction information.
The ATS605 is offered in a lead (Pb) free 4-pin SIP package
with an integrated back-basing magnet with a 100% matte tin
plated leadframe.
