This IC, developed by CMOS technology, is a high-accuracy hall effect latch IC that operates with a high-sensitivity, a highspeed 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.
