| HALL EFFECT SENOR IC | MAGNETIC SENSOR | OH34 / OH34N / OH44 Unipolar Hall IC 1. General Description OH34 Series Hall switches IC are small digital unipolar Hall-effect sensor ICs，which are designed to response S pole or N 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, which can change the magnetic field signal into a digital voltage output. With the typical feature of small size, stable performance, OH34 series are widely used in all kinds of position control, speed detection, flow detection occasion as a non-contact switch. 2. Features - 4V to 24V DC operation voltage - Open-Collector pre-driver - 25m A maximum sinking output current. - Reverse Polarity Protection - Respond to a single-pole (North or South). 3. Applications - Speed measurement - Home appliances - Position detection - Flow measurement 4.
