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 with movie, mobile phone and other applications involving crystal panels to detect the (front-back) location or determine the rotational direction of the panel. Unipolar Hall IC detects only N pole. This Hall IC product can be in tablets, smart phones, and other applications in order to detect open and close of the cover. Bipolar Latch Hall IC detects polarity change for both S and N pole. The operation is more stable compared to magnetic force detection (The duty on output pulse will be consistent). It is a perfect fit as an interface for wheel key and track ball applications.
