Sensor Operation Description
Power-On State
At power-on, the device is guaranteed to initialize in the OFF
state, with V
OUT
high.
First Edge Detection
The device uses the first two mechanical edges to synchronize
with the target features (tooth or valley) and direction of rotation
of the target. The device is synchonized by the third edge. The
actual behavior is affected by: target rotation direction relative to
the, target feature (tooth, rising edge, falling edge, or valley) that
is centered on the device at power-on, and fact that the sensor
powers-on in the OFF state,with V
OUT
high, regardless of the
eventual direction of target rotation. The interaction of these fac-
tors results in a number of possible power-on scenarios. These
are diagrammed in figure 6. In all start-up scenarios, the correct
number of output edges is provided, but the accuracy of the first
two edges may be compromised.

Target Motion Relative to Sensor
(A) Target relative movement
as shown in figure 3. Output
signal is high over the tooth.
(B) Target relative movement
opposite that shown in figure 3.
Output signal is low over the tooth.
Figure 6. Start-up Position And Relative Motion Effects on First Device Output Switching. Panel A shows the effects when the
target is moving from pin 1 toward pin 4 of the device; V
OUT
goes high at the approach of a tooth. When the target is moving
in the opposite direction, as in panel B, the polarity of the device output inverts; V
OUT
goes low at the approach of a tooth.
