The ATS625 true zero-speed gear tooth sensor is an optimized Hall IC and magnet
configuration packaged in a molded module that provides a manufacturer-friendly
solution for digital gear tooth sensing applications. The sensor assembly consists
of an over-molded package that holds together a samarium cobalt magnet, a
pole piece concentrator, and a true zero-speed Hall IC that has been optimized
to the magnetic circuit. This small package can be easily assembled and used in
conjunction with gears of various shapes and sizes.
The sensor incorporates a dual-element Hall IC that switches in response to
differential magnetic signals created by a ferrous target. Digital processing of the
analog signal provides zero-speed performance independent of air gap as well
as dynamic adaptation of device performance to the typical operating conditions
found in automotive applications (reduced vibration sensitivity). High-resolution
peak detecting DACs are used to set the adaptive switching thresholds of the
device. Switchpoint hysteresis reduces the negative effects of any anomalies in the
magnetic signal associated with the targets used in many automotive applications.
This sensor system is optimized for crank applications that utilize targets that
possess signature regions.
TheATS625 is provided in a 4-pin SIP. The Pb (lead) free option, available by
special request, has a 100% matte tin plated leadframe.
