Hall IC Series
Omnipolar Detection Hall ICs
(Polarity detection for
both S and N features dual outputs)
BU52004GUL, BU52014HFV
No.10045EDT01
●Description
The BU52004GUL and BU52014HFV are bipolar Hall ICs 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.
These Hall IC products 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
1) Omnipolar detection (polarity detection for both S and N features dual outputs)
2) Micropower operation (small current using intermittent operation method)
3) Ultra-compact CSP4 package(BU52004GUL)
4) Small outline package (BU52014HFV)
5) Line up of supply voltage
For 1.8V Power supply voltage (BU52014HFV)
For 3.0V Power supply voltage (BU52004GUL)
6) Polarity judgment and output on both poles (OUT1: S-pole output; OUT2: N-pole output)
7) High ESD resistance 8kV(HBM)
●Applications
Mobile phones, notebook computers, digital video camera, digital still camera, etc.
