S-5725 Series HIGH-SPEED www.ablic.com BIPOLAR HALL EFFECT LATCH IC ABLIC Inc., 2011-2021 Rev.2.6 00 This IC, developed by CMOS technology, is a high-accuracy hall effect latch 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 magnetic flux density and a polarity change. Using the S-5725 Series with a magnet makes it possible to detect the rotation status in various devices. High-density mounting is possible by using the small SOT-23-3 or the super-small SNT-4A packages. Due to its high-accuracy magnetic characteristics, this IC can make operation s dispersion in the system combined with magnet smaller.
