Description

These Hall-effect OH090U 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. The OH090Us 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 "O") with after a sufficient magnetic field from the south pole of a magnet approached the symbolized face of the OH090U (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 OH090U sensors ideal for applications in noncontact switching operations, brushless DC motors and for use with multiple pole magnets.
