This IC, developed by CMOS technology, is a high-accuracy Hall effect switch IC that operates with low current
consumption.
The output voltage changes when this IC detects the intensity level of magnetic flux density. Using this IC with a magnet makes it possible to detect the open / close in various devices.
High-density mounting is possible by using the small SOT-23-3 package or the super small SNT-4A package.
Due to its high-accuracy magnetic characteristics, this IC can make operation's dispersion in the system combined with magnet smaller.
