No.10045ECT03
●Description
The unipolar Detection Hall IC detects only either the N pole or S pole.
The output turns ON (active Low) upon detection.
●Features
1) Unipolar detection
2) Micropower operation (small current using intermittent operation method)
3) Ultra-compact CSP4 package (BU52002GUL, BU52003GUL)
4) Ultra- Small outline package (BU52012NVX)
5) Small outline package (BU52012HFV, BU52013HFV)
6) Line up of supply voltage
For 1.8V Power supply voltage (BU52012NVX, BU52012HFV, BU52013HFV)
For 3.0V Power supply voltage (BU52002GUL, BU52003GUL)
7) High ESD resistance 8kV(HBM)
●Applications
Mobile phones, notebook computers, digital video camera, digital still camera, etc.
●Lineup matrix

※10. B = Magnetic flux density
1mT=10Gauss
Positive (“+”) polarity flux is defined as the magnetic flux from south pole which is direct toward to the branded face of the sensor.
After applying power supply, it takes one cycle of period (TP) to become definite output.
Radiation hardiness is not designed.
