Description
The ATS616 gear-tooth sensor IC is a peak-detecting device
that uses automatic gain control and an integrated capacitor
to provide extremely accurate gear edge detection down to
low operating speeds. Each package consists of a high-tem-
perature plastic shell that holds together a samarium-cobalt
pellet, a pole piece, and a differential open-collector Hall 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 technology used for this circuit is Hall-effect based.
The chip incorporates a dual-element Hall IC that switches
in response to differential magnetic signals created by fer-
romagnetic targets. The sophisticated processing circuitry
contains an A-to-D converter that self-calibrates (normal-
izes) the internal gain of the device to minimize the effect of
air-gap variations. The patented peak-detecting filter circuit
eliminates magnet and system offsets and has the ability to
discriminate relatively fast changes such as those caused by
tilt, gear wobble, and eccentricities. This easy-to-integrate
solution provides first-tooth detection and stable operation
to extremely low rpm. The ATS616 can be used as a replace-
ment for the ATS612LSB, eliminating the external peak-
holding capacitor needed by the ATS612LSB.
