ATS642LSH

Two-Wire True Zero Speed Miniature Differential

Peak-Detecting Gear Tooth Sensor with Continuous Calibration

Features and Benefits

Description

▪ Running mode calibration for continuous optimization

▪ Single chip IC for high reliability

TheATS642LSHisanoptimizedHalleffectsensingintegrated

circuit and magnet combination that provides a user-friendly

solution for true zero-speed digital gear-tooth sensing in two-

wire applications. The sensor consists of a single-shot molded

plastic package that includes a samarium cobalt magnet, a

pole piece, and a Hall effect IC that has been optimized to the

magneticcircuit.Thissmallpackage, withoptimizedtwo-wire

leadframe, can be easily assembled and used in conjunction

with a wide variety of gear shapes and sizes.

▪ Internal current regulator for 2-wire operation

▪ Small mechanical size (8 mm diameter × 5.5 mm depth)

▪ Precise duty cycle signal over operating temperature range

▪ Large operating air gaps

▪ Automatic Gain Control (AGC) for air gap independent

switchpoints

▪ Automatic Offset Adjustment (AOA) for signal processing

optimization

The integrated circuit incorporates a dual element Hall effect

sensor and signal processing that switches in response to

differential magnetic signals created by ferrous gear teeth.

The circuitry contains a sophisticated digital circuit to reduce

magnet and system offsets, to calibrate the gain for air gap

independent switchpoints, and to achieve true zero-speed

operation. Signal optimization occurs at power-up through

the combination of offset and gain adjust and is maintained

throughout the operating time with the use of a running mode

calibration. The running mode calibration allows immunity to

environmental effects such as microoscillations of the target

or sudden air gap changes.

▪ True zero-speed operation

▪ Undervoltage lockout

▪ Wide operating voltage range

Package: 4-pin Module (suffix SH)

The regulated current output is configured for two wire

applications and the sensor is ideally suited for obtain-
