125°C OPERATION
HIGH-WITHSTAND VOLTAGE HIGH-SPEED
BIPOLAR HALL EFFECT LATCH IC
Rev.1.0
_01
This IC, developed by CMOS technology, is a bipolar Hall effect latch IC with high-withstand voltage, high-speed detection
and high-accuracy magnetic characteristics.
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 can make operation's dispersion in the system combined with
magnet smaller.
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.
For more information regarding our magnetic simulation service, contact our sales office.
