Omnipolar Detection Hall IC

(Dual Outputs for both S and N Pole Polarity Detection)

BU52737GWZ

General Description

Key Specifications

The omnipolar detection Hall IC incorporating a polarity

determination circuit enables separate operation (output) of

both the South and North poles. Using a magnet and the

Hall IC, detection of open and close of the cover are

possible in smart phones and tablets, and detection of

putting wireless earphones in a case, and detection of

front/back side or rotational direction are possible in digital

cameras and other applications involving display panels.
