Omnipolar Detection Hall IC

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

BU52075GWZ

General Description

Key Specifications

The BU52075GWZ 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.
