FOR AUTOMOTIVE 125°C OPERATION
HIGH-WITHSTAND VOLTAGE HIGH-SPEED
UNIPOLAR DETECTION TYPE HALL EFFECT SWITCH IC
Rev.1.7_01
This IC, developed by CMOS technology, is a high-accuracy Hall effect switch 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. Using this IC with a magnet
makes it possible to detect the open / close and rotation status in various devices.
This IC includes a reverse voltage protection circuit and an output current limit circuit.
High-density mounting is possible by using the small SOT-23-3 package.
Due to its high-accuracy magnetic characteristics, this IC can make operation's dispersion in the system combined with
magnet smaller.
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.
Caution This product can be used in vehicle equipment and in-vehicle equipment. Before using the product in the
purpose, contact to ABLIC Inc. is indispensable.
