LOW VOLTAGE OPERATION
OMNIPOLAR / UNIPOLAR DETECTION TYPE
HALL EFFECT SWITCH IC WITH SWITCHABLE DETECTION POLE FUNCTION
Rev.1.1
_01
This IC, developed by CMOS technology, is a high-accuracy Hall effect switch 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.
ABLIC Inc. 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.
For more information regarding our magnetic simulation service, contact our sales office.
