PRELIMINARY INFORMATION
(subject to change without notice)
October 20, 2000
The ATS640JSB Hall-effect gear-tooth sensor is a peak detecting device
that uses internal gain control to provide extremely stable duty cycles down to
zero speed. Each sensor subassembly consists of a high-temperature plastic
shell that holds together a samarium-cobalt magnet, a pole piece, and a true
zero-speed BiCMOS differential Hall-effect gear-tooth sensor IC that has been
optimized to the magnetic circuit. This small package can be easily assembled
and used in conjunction with a wide variety of gear shapes and sizes.
The gear-sensing technology used for this sensor subassembly is Hall-
effect based. The sensor incorporates a dual-element Hall IC that switches in
response to differential magnetic signals created by a ferrous target. The
sophisticated self-calibrating digital-processing circuitry normalizes the
internal gain of the device to minimize the effect of air gap variations. and to
reduce vibration sensitivity. The circuit eliminates magnet and system offsets
such as those caused by tilt yet provides zero-speed detection capabilities
without the associated running jitter inherent in classical digital solutions.
This sensor system is ideal for use in gathering speed, position, and timing
information using gear-tooth-based configurations. The ATS640JSB is
particularly suited to those applications that require extremely accurate duty
cycle control or accurate edge detection. The lower vibration sensitivity also
makes this device extremely useful for transmission speed sensing.
