OH3141L OH44L Unipolar Hall effect IC datasheet

Product description

These Hall-effect switches are monolithic integrated circuits with tighter magnetic specifications, designed to operate continuously over extended temperatures to +150°C, and are more stable with both temperature and supply voltage changes. Each device includes a voltage regulator for operation with supply voltages of 4.5 to 24 volts, reverse battery protection diode, quadratic Hall-voltage generator, temperature compensation circuitry, small-signal amplifier, Schmitt trigger, and an open-collector output to sink up to 50 mA.


  • 5V to 24V DC operation voltage
  • Responding to a single-pole
  • Open-Collector sinking type
  • 50mA maximum sinking output current
  • Reverse Polarity Protection
  • Good temperature performance
  • Higher sensitivity
  • Compatible with Digital Logic


  • The brushless DC motor, DC fans, DC water pump
  • The home appliance control panel
  • sewing equipment, textile machinery
  • speed sensor, position detecting, counting and
  • The flow sensor, flow meter
  • The auto-ignition, safety alarm device
  • other industrial control fields
