FOR AUTOMOTIVE 125°C OPERATION HIGH-WITHSTAND VOLTAGE

HIGH-SPEED UNIPOLAR DETECTION TYPE HALL EFFECT SWITCH IC

© SII Semiconductor Corporation, 2013-2017

1

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.

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.

Caution This product can be used in vehicle equipment and in-vehicle equipment. Before using the product in the

purpose, contact to SII Semiconductor Corporation is indispensable.
