Characteristic Allowable Signal Amplitude Variation
The colored area in figure 10 shows B
SOA
, the safe operating
area of allowable magnetic signal amplitude within which the IC
will continue output switching. The output duty cycle is wholly
dependent on the magnetic signature of the target across the air
gap range of movement, and may not always be within specifi-
cation throughout the entire operating region (to B
DIFF
(max)).
Signal amplitude changes may be due to deflection (relative air
gap change between Hall element and target), target eccentricity,
magnet temperature coefficient or a combination thereof.
The axis parameters for the chart in figure 10 are defined in fig-
ure 11. As an example, assume the case where the signal changes
from the nominal at the installed air gap (B
CAL
) within the range
defined by an increase factor of B
DIFF
(max) / B
CAL
 = 3.0, and a
decrease of B
DIFF(lim)
 / B
CAL
 = 0.75. This case is plotted with an
x in figure 10.
