APPLICATIONS INFORMATION
Power-on state operation.
The device is guaranteed
to power on (power up) in the off state (high output
voltage) regardless of the presence or absence of a gear
tooth. Note that the circuit is ready to accurately detect the
first gear edge that results in a tooth-to-valley transition
after the circuit has successfully powered on.
Under-voltage lockout.
If the supply voltage falls
below the under-voltage lockout (V
CC(UV)
), the device
output will turn off (high output voltage) and stay off
irrespective of the state of the magnetic field. This pre-
vents false signals caused by under-voltage conditions
from propagating through to the output of the sensor.
Output.
The output of the module is a short-circuit-
protected open-collector stage capable of sinking 20 mA.
An external pull-up (resistor) to a supply voltage of not
more than 24 V must be supplied.
Output polarity.
The output of the device will switch
from off to on as the leading edge of the target passes the
sensor in the direction indicated (pin 4 to pin 1), which
means that the output current will be low when the unit is
facing a tooth. If rotation is in the opposite direction (pin
1 to pin 4), the output of the device will switch from on to
off as the leading edge of the target passes the sensor,
which means that the output voltage will be low when the
unit is facing a tooth.
Power supply protection.
The device contains an on-
chip regulator and can operate over a wide supply voltage
range. For devices that need to operate from an unregu-
lated power supply, transient protection should be added
externally. For applications using a regulated line, EMI/
RFI protection is still required. Incorrect protection can
result in unexplained pulses on the output line, providing
inaccurate sensing information to the user.
EMI protection circuitry can easily be added to a PC
board for use with this device. Provisions have been made
for easy mounting of this board on the back of the unit.
PC board installation parallel to the device axis is also
possible.
