Description
TheATS665truezero-speedgeartoothsensorICisanoptimized
Hall IC/rare earth pellet configuration designed to provide a
user-friendlysolutionfordigitalgeartoothsensingapplications.
The over-molded package, holds together a samarium cobalt
pellet, a pole piece 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 ferromagnetic target. The IC contains a sophisticated
compensating circuit designed to reduce the detrimental effects
of magnet and system offsets. Digital processing of the analog
signal provides zero speed performance independent of air
gap and also 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. Hysteresis in the thresholds reduces the negative effects
of any anomalies in the magnetic signal associated with the
targets used in many automotive applications.
