OH3020 Unipolar hall IC Datasheet

Product description

OH3020 is a unipolar Hall-Effect IC, which is for contactless switching applications. The device includes an on-chip Hall voltage generator for magnetic sensing, an amplifier that amplifies the Hall voltage, a Schmitt trigger to provide switching hysteresis for noise rejection, and open-collector output.

Features

  • Respond to a South pole
  • 4V to 24V DC operation voltage
  • 25mA maximum sinking output current.
  • Open-Collector pre-driver
  • Reverse Polarity Protection

Applications

  • Speed measurement
  • Home appliances
  • Position detection
  • Flow measurement
