OH34 - Unipolar Hall IC
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 amplif
