Description:
These Hall-effect devices contain a monolithic integrated circuit which incorporates a Hall element, a linear
amplifier, a threshold amplifier, and Schmitt trigger on a single Hallogic® silicon chip. Included on-chip is a band
gap voltage regulator to allow operation with a wide range of supply voltages. These devices feature logic level
output and provide up to 21 mA of sink current. This allows direct driving of more than 7 TTL loads or any
standard logic family using power supplies ranging from 4.5 to 24 volts. Output amplitude is constant at switching
frequencies from DC to over 200 kHz.
The Uni-Polar turns on with a (logic level “0”) after a sufficient magnetic field from the south pole of a magnet
approached the symbolized face of the device (Operating Point) and turns off (logic level “1”) after the magnetic
field reached a minimum value. The Bi-Polar latch device turns on (logic level “0”) in the presence of a magnetic
south pole and turn off (logic level “1”) when subjected to a magnetic north pole. Both magnetic poles are
necessary for operation for Bi-Polar devices. This feature makes these sensors ideal for applications in non-
contact switching operations, brushless DC motors and for use with multiple pole magnets.
