The ATS665 true zero-speed gear tooth sensor is an optimized
Hall IC/magnet configuration packaged in a molded module that
provides a user-friendly solution for digital gear tooth sensing
applications. The sensor module consists of an over-molded
package, which holds together a samarium cobalt magnet, a pole
piece and a true zero-speed Hall IC that has been optimized to the
magnetic circuit. This small package can be easily assembled and
used in conjunction with gears of various shapes and sizes.
The sensor incorporates a dual element Hall IC that switches in
response to differential magnetic signals created by a ferrous
target. The IC contains a sophisticated compensating circuit
designed to reduce the detrimental effects of magnet and system
offsets. Digital processing of the analog signal provides zero speed
performance independent of air gap and also dynamic adaptation of
device performance to the typical operating conditions found in
automotive applications (reduced vibration sensitivity). High-
resolution peak detecting DACs are used to set the adaptive
switching thresholds of the device. Hysteresis in the thresholds
reduces the negative effects of any anomalies in the magnetic
signal associated with the targets used in many automotive
applications.
This sensor’s ability to provide tight duty cycle at high speeds
and over a wide temperature range makes it ideal for transmission
and industrial speed applications. The ATS665 is available in the
SG package in the automotive temperature range, -40° to 150° (L).
