Vibration suppression algorithm:
The magnetic signal amplitude and the direction information is used for detection of
parasitic magnetic signals. Unwanted magnetic signals can be caused by angular or
airgap vibrations for instance. If an input signal is clearly detected as a vibration signal,
the output of pulses will be suppressed.
A magnetic input signal is classified as parasitic vibration signal if
a. the speed signal amplitude is smaller than the internal hysteresis or
b. the direction signal amplitude is smaller than the internal limit or
c. the direction signal consists of alternating left/right information
The quality of vibration suppression (according a & b) depends on the hysteresis limits
and on the magnitude of the magnetic signal. The bigger the hysteresis the better the
suppression of parasitc signals.
For parasitic signals where items above (a. to c.) are not clearly applicable or at other
more rare cases (e.g. IC startup) vibration suppression is not guaranteed. The
performance of the direction detection and vibration suppression algorithm depends on
the used magnetic circuit and as well on the used target wheel and need to be evaluated.
Please ask for application support if you have questions on the vibration suppresion algorithm.
Package information:
Pure tin covering (green lead plating) is used. Lead frame material is Wieland K62 (UNS:
C18090) and contains CuSn1CrNiTi. Product is RoHS (Restriction of Hazardous
Substances) compliant and marked with letter G in front of the data code marking and
may contain a data matrix code on the rear side of the package (see also information
note 136/03). Please refer to your key account team or regional sales if you need further
information.
