Hall IC Series
Unipolar Detection
Hall ICs
BU52002GUL,BU52003GUL,BU52012HFV,BU52013HFV
No.10045EBT03
●Description
The unipolar Detection Hall IC detects only either the N pole or S pole. The output turns ON (active Low) upon detection.
It is most suitable for strictly unipole detection and when lower power consumption is desired.
●Features
1) unipolar detection
2) Micropower operation (small current using intermittent operation method)
3) Ultra-compact CSP4 package (BU52002GUL,BU52003GUL)
4) Small outline package (BU52012HFV,BU52013HFV)
5) Line up of supply voltage
For 1.8V Power supply voltage(BU52012HFV,BU52013HFV)
For 3.0V Power supply voltage (BU52002GUL,BU52003GUL)
6) High ESD resistance 8kV(HBM)
●Applications
Mobile phones, notebook computers, digital video camera, digital still camera, etc.

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 (T
