Description
The ATS625 true zero-speed gear tooth sensor IC is an optimized
Hall IC and rare earth pellet configuration that provides a
manufacturer-friendly solution for digital gear tooth sensing
applications. The over-molded package holds together a
samarium cobalt pellet, 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 device 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 device is optimized for
crank applications that utilize targets that possess signature
regions.
The ATS625 is provided in a 4-pin SIP. It is lead (Pb) free,
with 100% matte tin plated leadframe.
