Low Voltage Operation Omnipolar / Unipolar Detection Type Hall Effect Switch IC S-5717 Series

The S-5717 Series, developed by CMOS technology, is a high-accuracy Hall effect switch IC that operates at a low voltage and low current consumption.
The output voltage changes when the S-5717 Series detects the intensity level of flux density. Using the S-5717 Series 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 low voltage operation and low current consumption, the S-5717 Series is suitable for battery-operated portable devices. Also, due to its high-accuracy magnetic characteristics, the S-5717 Series can make operation’s dispersion in the system combined with magnet smaller.
