ATS616LSG

Dynamic Self-Calibrating Peak-Detecting Differential

Hall Effect Gear Tooth Sensor IC

Description

Features and Benefits

• Self-calibrating for tight timing accuracy

• First-tooth detection

• Immunity to air gap variation and system offsets

• Eliminates effects of signature tooth offsets

• Integrated capacitor provides analog peak and valley

information

• Extremely low timing-accuracy drift with temperature

changes

• Large air gap capability

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.

• Small, integrated package

• Optimized magnetic circuit

• Undervoltage lockout (UVLO)

• Wide operating voltage range

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.

Package: 4-pin SIP (suffix SG)
