TRUE ZERO-SPEED, HALL-EFFECT

ADAPTIVE GEAR-TOOTH SENSOR

The ATS660LSB is an ideal gear-tooth sensor solution for uniform

teeth targets as found in today’s demanding transmission applications.

This digital differential Hall-effect sensor is the choice when repeatabil-

ity and timing accuracy count. The ATS660LSB incorporates patented

self-calibration circuitry (U.S. Pat. 5,917,320) that nulls out the effects

of installation air gap, ambient temperature, and magnet offsets to

provide superior timing accuracy with symmetrical targets over large

operating air gaps — typical of targets used in speed-sensing applica-

tions (pitches varying from below 0.5 to over 1.2 teeth per diametric

millimeter). The self-calibration at power up keeps the performance

optimized over the life of the sensor. The ATS660LSB has an open-

collector output for direct digital interfacing with no further signal

processing required. This device is available in a small 9-mm diameter

by 7-mm long package for optimal manufacturing.

Pin 1 = Supply

Pin 2 = Output

Pin 3 = Internal Connection

Pin 4 = Ground

Dwg. AH-006-4

The integrated circuit incorporates a dual-element Hall-effect

sensor and signal processing that switches in response to differential

magnetic signals created by the ferrous gear teeth. The circuitry

contains a sophisticated digital circuit to eliminate magnet and system

offsets and to achieve true zero-speed operation . D-to-A converters are

used to adjust the device gain at power on and to allow air-gap indepen-

dent switching, which greatly reduces vibration sensitivity of the

device.
