Self-Calibrating, Zero-Speed Differential GTS with Continuous Update
ATS643LSH
Start Mode Hysteresis
. This feature helps to ensure optimal
self-calibration by rejecting electrical noise and low-amplitude
target vibration during initialization. This prevents AGC from
calibrating the sensor on such spurious signals. Calibration can
be performed using the actual target features.
A typical scenario is shown in figure 6. The hysteresis, PO
HYS
,
is a minimum level of the peak-to-peak amplitude of the internal
analog electrical signal, V
PROC
, that must be exceeded before the
ATS643 starts to compute switchpoints.
Figure 6. Operation of Start Mode Hysteresis
Position 1. At power-on, the ATS643 begins sampling V
PROC
.
Position 2. At the point where the Start Mode Hysteresis is exceeded, the device begins to establish switching thresholds (B
OP
and B
RP
) using the Con-
tinuous Update algorithm. After this point, Start Mode Hysteresis is no longer a consideration. Note that a valid V
PROC
value exceeding the Start Mode
Hysteresis can be generated either by a legitimate target feature or by excessive vibration.
Position 3. In this example, the first switchpoint transition is through B
OP
. and the output transitions from high to low.
If the first switchpoint transition had been through B
RP
(such as position 4), no output transition would occur because I
OUT
already would be in the high
polarity. The first transition would occur at position 5 (B
OP
).
