This IC, developed by CMOS technology, is a high-accuracy hall effect latch IC that operates with high temperature and high-withstand voltage.
The output voltage changes when this IC detects the intensity level of magnetic flux density and a polarity change. Using this IC with a magnet makes it possible to detect the rotation status in various devices.
This IC includes an output current limit circuit.
High-density mounting is possible by using the small SOT-23-3S package.
Due to its high-accuracy magnetic characteristics, this IC enables the user to reduce the operational variation in the system.
