measurement
• Enhanced EMC performance
DESCRIPTION
The ATS627 is a true zero-speed gear tooth sensor IC consisting
of an optimized Hall IC and rare earth pellet configuration in
a single overmolded package. The integrated circuit provides
a manufacturer-friendly solution for digital gear tooth sensing
applications. This small package can be easily assembled and
used in conjunction with gears of various shapes and sizes.
The dual-element Hall IC 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.
High-resolution peak detecting DACs are used to set the
adaptive switching thresholds of the device. Bounded tracking
and switchpoint hysteresis reduce the negative effects of any
anomalies in the magnetic signal associated with the targets
used in many automotive applications. This sensor IC system
is optimized for engine crank applications that use targets
possessing signature regions.
This device is available in a lead (Pb) free 4-pin SIP package
(SG) with a 100% matte tin-plated leadframe.
PACKAGE: 4-pin SIP (suffix SG)
