Omnipolar Detection Hall IC - BU52077GWZ (New)

The BU52077GWZ is omnipolar Hall IC incorporating a polarity determination circuit that enables separate operation (output) of both the South and North poles. The polarity judgment is based on the output processing configuration. This Hall IC product can be in tablets, smart phones, and other applications in order to detect open and close of the cover. And this Hall IC product can be in digital video cameras and other applications involving display panels in order to detect the front/back location or determine the rotational direction of the panel.
