Omnipolar Detection Hall IC
(Dual Outputs for both S and N Pole Polarity Detection)
BU52177GXZ
General Description
Key Specifications
The BU52177GXZ is omnipolar Hall IC 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.
