4. AOH N3075U f RS Product Bulletin OHN3075U May 1996 PD OPTEK Hallogic Bipolar Hall Effect Sensors Latches Types OHN3075U OHS3075U Features e Designed for use in brushless DC motors e Operates over a broad range of supply voltages e Excellent temperature stability to operate in harsh environments e Drive capability up to 7 TTL loads Description The OHN3075U and OHS3075U each 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 bandgap voltage regulator to allow operation with a wide range of supply voltages The devices feature logic level output and provides 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 100 kHz These devices turn 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 so they are referred to as Bipolar or Latching This feature makes these sensors ideal for applications in brushless DC motors and for use with multiple pole magnets Optek Technology Inc 1215 W Crosby Road 182 4 62 500 12 70 176 4 4
