OH137 Datasheet | 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 4.
