This table shows the various Hall ICs that ROHM offers. Omnipolar detection Hall ICs can detect both S-and N-pole magnetic fields, simplifying magnet management. Omnipolar Detection Hall IC with polarity discrimination includes a polarity determination circuit that enables operation (output) on both the S- and N-poles, with the polarity judgment based on the output processing configuration. This Hall IC product can be in applications involving crystal panels to detect the front-back location or to determine the rotational direction of the product. Unipolar Hall IC detects only N pole. Unipolar sensors can be in doors, covers, and other applications in order to detect open and close of the object. Bipolar Latch Hall IC detects polarity change for both S and N pole. The operation is more stable compared to magnetic force detection, as the duty on output pulse will be consistent.
