S-5712A/B/C Series LOW VOLTAGE OPERATION OMNIPOLAR / UNIPOLAR DETECTION TYPE www.ablic.com HALL EFFECT SWITCH IC ABLIC Inc., 2010-2021 Rev.5.2 00 This IC, 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 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 or the super-small SNT-4A package. Due to its low voltage operation and low current consumption, this IC is 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.
