Super Low Current Consumption Low Voltage Operation Omnipolar Detection Type Hall Effect Switch IC S-5719 Series

Product Overview Standard Circuit Example SNT-4A (PF004-A)

This IC, developed by CMOS technology, is a high-accuracy Hall effect switch IC that operates with super low current consumption and low voltage.
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 super-small SNT-4A package.
Due to its super low current consumption and low voltage, this IC is most suitable for battery-operated portable devices. Also, due to its high-accuracy magnetic characteristics, this IC can make operation's dispersion in the system combined with magnet smaller.
