Omnipolar Detection Hall IC

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

BU52074GWZ

General Description

Key Specifications

The omnipolar detection Hall IC is incorporating a

polarity determination circuit that enables separate

operation (output) of both the South and North poles.

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.
