DEVICE DESCRIPTION
Module description.
The ATS622LSB true zero-speed
gear-tooth sensor system is a Hall IC plus magnet configu-
ration that is fully optimized to provide digital detection of
gear-tooth* edges in a small package size. The sensor is
packaged in a miniature plastic housing that has been
optimized for size, ease of assembly, and
manufacturability. High operating-temperature materials
are used in all aspects of construction.
The use of the sensor is simple. After correct power is
applied to the component, it is capable of instantly provid-
ing digital information that is representative of the profile
of a rotating gear. No additional optimization or process-
ing circuitry is required. This ease of use should reduce
design time and incremental assembly costs for most
applications.
Sensing technology.
The gear-tooth sensor module
contains a single-chip differential Hall-effect sensor IC, a
samarium-cobalt magnet, and a flat ferrous pole piece.
The Hall IC consists of two Hall elements spaced 2.2 mm
apart, located so as to measure the magnetic gradient
created by the passing of a ferrous object (a gear tooth).
The two elements measure the field gradient and convert it
to a voltage that is then processed to provide a digital
output signal.

* In application, the terms “gear” and “target” are often inter-
changed. However, “gear” is preferred when motion is trans-
ferred.

Internal electronics.
The ATS622LSB is a self-
calibrating sensor that contains two Hall-effect elements, a
temperature-compensated amplifier, and offset cancella-
tion circuitry. Also contained in the device is a voltage
regulator to provide supply rejection over the operating
voltage range.
The self-calibrating circuitry is unique. After power up,
the device measures the peak-to-peak magnetic signal and
adjusts the gain using an on-chip D-to-A converter to
make the internal signal amplitude constant independent of
the installation air gap of the sensor. This feature allows
air-gap-independent operational characteristics.
