Unipolar Hall IC S pole detection ROHM BU52012NVX-TR with low supply current and CMOS output package
Hall ICs Unipolar Detection
The BU52002GUL, BU52003GUL, BU52012NVX, BU52012HFV, and BU52013HFV are unipolar detection Hall ICs designed to detect either the N pole or S pole. Upon detection, the output turns ON (active Low). These devices feature micropower operation through an intermittent operation method, ultra-compact packaging options (CSP4, ultra-small outline, and small outline), and a lineup of supply voltages for both 1.8V and 3.0V power supplies. They also boast high ESD resistance (8kV HBM).

Note: 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.
