The BU52000 Series from ROHM Electronics, San Diego, CA, are tiny Hall ICs that integrate magnetic detection and connection circuits onto a single chip. Monopole and dipole detection-type ICs are available in the VCSP50L1 chip-scale package type. Monopole detection ICs (BU52002GUL and BU52003GUL) offer 1 output pin and S- or N-pole detection, respectively. Dipole detection ICs (BU52001GUL and BU52004GUL) offer 1 or 2 output pins, respectively. The BU52004GUL offers S-pole detection on 1 output and N-pole detection on the other. Applications include opening and closing detection in folding-style mobile phones.
