The simplest form of magnet that will operate these devices is a ring
magnet, as shown below. Other methods of operation are possible.
Dwg. A-11,899
OPERATION
In operation, the output transistor is OFF until the strength of the mag-
netic field perpendicular to the surface of the chip exceeds the threshold or
operate point (BOP). When the field strength exceeds BOP, the output transis-
tor switches ON and is capable of sinking 25 mA of current.
The output transistor switches OFF when magnetic field reversal results
in a magnetic flux density below the OFF threshold (BRP). This is illustrated
in the transfer characteristics graph (A3187* shown).
Note that the device latches; that is, a south pole of sufficient strength
will turn the device ON. Removal of the south pole will leave the device ON.
The presence of a north pole of sufficient strength is required to turn the
device OFF.

Although sensor location is accurate to three
sigma for a particular design, product improve-
ments may result in small changes to sensor
location.
