TPOS (True Power-On State) Operation
Under specified operating conditions, the devices are guaran-
teed to attain a specified output voltage polarity at power-on, in
relation to the target feature nearest the device at that time. Both
devices offer the options of either high or low polarity over ini-
tial tooth or valley. This polarity also applies throughout device
operation.
Start-Up Detection
These devices provide an output polarity transition at the first
mechanical edge after power-on.
Undervoltage Lockout
When the supply voltage falls below the undervoltage lockout
level, VCCUV, the device switches to the OFF state. The device
remains in that state until the voltage level is restored to to the
VCC operating range. Changes in the target magnetic profile
have no effect until voltage is restored. This prevents false sig-
nals caused by undervoltage conditions from propagating to the
output of the sensor.
Power Supply Protection
The ATS673 and ATS674 contain an on-chip regulator and can
operate over a wide range of supply voltage levels. For applica-
tions using an unregulated power supply, transient protection
must be added externally. For applications using a regulated
supply line, EMI and RFI protection may still be required. The
circuit shown in figure 5 is the basic configuration required for
proper device operation. Contact Allegro field applications engi-
neering for information on the circuitry required for compliance
to various EMC specifications.
Internal Electronics
These devices contain a self-calibrating Hall effect IC that
provides a Hall element, a temperature compensated ampli-
fier, and offset cancellation circuitry. The IC also contains a
voltage regulator that provides supply noise rejection over the
operating voltage range. The Hall transducers and the electron-
ics are integrated on the same silicon substrate by a proprietary
BiCMOS process. Changes in temperature do not greatly affect
this device due to the stable amplifier design and the offset rejec-
tion circuitry.
