Low Voltage Operation Omnipolar / Unipolar Detection Type Hall Effect Switch IC with Switchable Detection Pole Function S-5718 Series

This IC, developed by CMOS technology, is a high-accuracy Hall effect IC with switchable detection pole function 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 of the polarity according to the input pin status. The inclusion of a switchable detection pole function makes it possible to reduce the number of parts and realize a variety of different systems by using this IC with a magnet. High-density mounting is possible by using 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. Its high-accuracy magnetic characteristics also allow this IC to reduce operation dispersion in magnet combination systems.

SII Semiconductor Corporation offers a “magnetic simulation service” that provides the ideal combination of magnets and our Hall effect ICs for customer systems. Our magnetic simulation service will reduce prototype production, development period and development costs. In addition, it will contribute to optimization of parts to realize high cost performance.
