Applications.
Allegro's pole-independent sensing technique
allows for operation with either a north pole or south pole
magnet orientation, enhancing the manufacturability of the
device. The state-of-the-art technology provides the same
output polarity for either pole face.
It is strongly recommended that an external bypass
capacitor be connected (in close proximity to the Hall sensor)
between the supply and ground of the device to reduce both
external noise and noise generated by the chopper-stabilization
technique. This is especially true due to the relatively high
impedance of battery supplies.
The simplest form of magnet that will operate these
devices is a bar magnet with either pole near the branded
surface of the device. Many other methods of operation are
possible. Extensive applications information on magnets and
Hall-effect sensors is also available in the
