Functional Description
Hall Technology
This single-chip differential Hall-effect sensor IC possesses
two Hall elements spaced at a fixed distance (1.5 mm), which
simultaneously are affected by the magnetic profile of the target,
and generate a differential internal analog voltage, V
PROC
, that is
processed for precise switching of the digital output signal.
The Hall IC is self-calibrating and also possesses a temperature
compensated amplifier and offset compensation circuitry. Its
voltage regulator provides supply noise rejection throughout the
operating voltage range. Changes in temperature do not greatly
affect this device due to the stable amplifier design and the offset
compensation circuitry. The Hall transducers and signal process-
ing electronics are integrated on the same silicon substrate, using
a proprietary BiCMOS process.
Target Profiling
An operating device is capable of providing digital informa-
tion that is representative of the magnetic features on a rotating
target. The waveform diagram shown in figure 3 represents the
automatic translation of the magnetic profile to the digital output
signal of the IC.
Output Polarity
Figure 3 shows the output polarity for the orientation of the target
and package shown in figure 2. The target direction of rotation
shown is perpendicular to the leads, across the face of the device,
from pin 1 to pin 4. This results in the IC output switching from
high, I
CC(HIGH)
, to low I
CC(LOW)
, as the leading edge of a tooth (a
rising mechanical edge, as detected by the IC) passes the branded
face. In this configuration, the device output current switches to
its low polarity when a tooth is the target feature nearest to the
branded face. If the direction of rotation is reversed, then the
output polarity inverts.
Note: the translated output voltage polarity is dependent on the
position of a sense resistor, R
SENSE
(see figure 4).

Figure 2. This left-to-right (pin 1 to pin 4) direction of target rotation results
in a low output signal when a tooth of the target gear is nearest the face
of the package (see Figure 3). A right-to-left (pin 4 to pin 1) rotation inverts
the output signal polarity.
