Datasheet
Omnipolar Detection Hall IC
(Polarity detection for both S and N features dual outputs)
BU52058GWZ
●General Description
The BU52058GWZ is omnipolar Hall IC incorporating a
polarity determination circuit that enables operation
(output) on both the S- and N-poles, with the polarity
judgment based on the output processing configuration.
This Hall IC product can be in with movie, mobile phone
and other applications involving crystal panels to detect
the (front-back) location or determine the rotational
direction of the panel.
●Features
Omnipolar detection (polarity detection for both S
and N features dual outputs)
Micro power operation (small current using
intermittent operation method)
Ultra-compact CSP4 package (UCSP35L1)
Polarity judgment and output on both poles
(OUT1: S-pole output; OUT2: N-pole output)
High ESD resistance 8kV(HBM)
