Please contact each Web shop for details such as availability of online samples.

This IC, developed by CMOS technology, is a high-accuracy Hall effect switch IC that operates at a low voltage with a highspeed detection. 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.

We offer a “magnetic simulation service” that provides the ideal combination of magnets and our Hall 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.
