The ATS642LSH is an optimized Hall effect sensing integrated 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 magnetic circuit. This small
package, with optimized two-wire leadframe, can be easily assembled and used in
conjunction with a wide variety of gear shapes and sizes.
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 run-
ning mode calibration allows immunity to environmental effects such as microos-
cillations of the target or sudden air gap changes.
The regulated current output is configured for two wire applications and the
sensor is ideally suited for obtaining speed and duty cycle information in ABS
(antilock braking systems). The 1.5 mm Hall element spacing is optimized for fine
pitch gear-tooth-based configurations. The package is lead (Pb) free, with 100%
matte tin leadframe plating.
