S-57B1 Series 125 C OPERATION HIGH-SPEED www.ablic.com UNIPOLAR DETECTION TYPE HALL IC www.ablicinc.com ABLIC Inc., 2011-2016 Rev.3.0 01 This IC, developed by CMOS technology, is a high-accuracy Hall IC that operates with a high-sensitivity, a high-speed detection and low current consumption. The output voltage changes when this IC detects the intensity level of flux density. Using this IC with a magnet makes it possible to detect the open / close and rotation state in various devices. High-density mounting is possible by using the small SOT-23-3 package. Due to its high-accuracy magnetic characteristics, this IC can make operations dispersion in the system combined with magnet smaller.
