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
