Description
The ATS643 is an optimized combination of integrated circuit
and magnet that provides a manufacturer-friendly solution
for true zero-speed digital gear-tooth sensing in two-wire
applications. The device consists of a single-shot molded
plastic package that includes a samarium cobalt magnet, a
pole piece, and a Hall-effect IC that has been optimized to the
magnetic circuit and the automotive environment. This small
package can be easily assembled and used in conjunction with
a wide variety of gear shapes and sizes.
The integrated circuit incorporates a dual element Hall-effect
sensor with signal processing circuitry that switches in response
to differential magnetic signals created by rotating ferrous
targets. The device contains a sophisticated compensating
circuit to eliminate magnet and system offsets immediately
at power-on. Digital tracking of the analog signal is used
to achieve true zero-speed operation, while also setting the
device switchpoints. The resulting switchpoints are air gap
independent, greatly improving output and duty cycle accuracy.
The device also uses a continuous update algorithm to fine-
tune the switchpoints while in running mode, maintaining
