DEVICE DESCRIPTION — Continued
Peak-Detecting vs. AC-Coupled Filters.
High-pass
filtering (normal ac coupling) is a commonly used tech-
nique for eliminating circuit offsets. AC coupling has errors
at power on because the filter circuit needs to hold the
circuit zero value even though the circuit may power on
over a large signal. Such filter techniques can only
perform properly after the filter has been allowed to settle,
which is typically greater than one second. Also,
high-pass filter solutions cannot easily track rapidly
changing baselines such as those caused by eccentrici-
ties. Peak detection switches on the change in slope
of
the signal and is baseline independent at power up and
during running.
Peak Detecting vs. Zero-Crossing Reference.
The
usual differential zero-crossing sensors are susceptible to
false switching due to off-center and tilted installations,
which result in a shift in baseline that changes with air gap.
The track-and-hold peak-detection technique ignores
baseline shifts versus air gaps and provides increased
immunity to false switching. In addition, using
track-and-hold peak-detecting techniques, increased air
gap capabilities can be expected because a peak detector
utilizes the entire peak-to-peak signal range as compared
to zero-crossing detectors that switch on one-half the
peak-to-peak signal.
NOTE — “Baseline” refers to the zero-gauss differential
where each Hall-effect element is subject to the same
magnetic field strength.
Power-On Operation
. The device will power on in the
OFF state (output high) irrespective of the magnetic field
condition. The power-up time of the circuit is no greater
than 500
μ
s. The circuit is then ready to accurately detect
the first target edge that results in a HIGH-to-LOW transi-
tion.
Under-Voltage Lockout.
When the supply voltage is
below the minimum operating voltage (V
CC(UV)
), the
device is OFF and stays OFF irrespective of the state of
the magnetic field. This prevents false signals, which may
be caused by under-voltage conditions (especially during
turn on), from appearing at the output.
Output
. The device output is an open-collector stage
capable of sinking up to 20mA. An external pull-up
(resistor) to a supply voltage of not more than 24V must
be supplied.
