DEVICE DESCRIPTION
Subassembly description.
The ATS660LSB true
zero-speed gear-tooth sensor system is a Hall IC + magnet
configuration 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 subassem-
bly 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 ATS660LSB 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.
