OH37
OH37 is Unipolar Hall-effect manufactured by OUZHUO.
Description
OH37 Series Hall-effect ICs response to S pole from a permanent magnet or an electromagnet. They internally consist of a reverse voltage protection device, voltage regulator, Hall voltage generator, a differential amplifier, Schmitt trigger, and the open collector output level. While the magnetic flux density (B) is larger than the threshold Bop, the OUT pin turns on (low), when B < Brp, the OUT pin goes into “ off ” state. SIP and SMD types are available.
2. Features
- Respond to a South pole
- 4V to 24V DC operation voltage
- 25m A maximum sinking output current.
- Open-Collector pre-driver
- Reverse Polarity Protection
3. Applications
- Speed measurement
- Home appliances
- Position detection
- Flow measurement
