Description
The ATS667 is a true zero-speed gear tooth sensor IC consisting
of an optimized Hall IC-rare earth pellet configuration in a
single overmolded package. The unique IC and package design
provides a user-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 device incorporates a dual element Hall IC that switches
in response to differential magnetic signals created by a ferro-
magnetic target. The IC contains a sophisticated compensating
circuit designed to eliminate 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.
The ATS667 is optimized for transmission applications. It is
available in a lead (Pb) free 4-pin SIP package with a 100%
matte tin plated leadframe.
