S-5731 Series HIGH-WITHSTAND VOLTAGE HIGH-SPEED UNIPOLAR DETECTION TYPE www.ablic.com www.ablicinc.com HALL EFFECT SWITCH IC ABLIC Inc., 2014-2017 Rev.1.1 01 This IC, developed by CMOS technology, is a unipolar detection type Hall effect switch 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. Using this IC with a magnet makes it possible to detect the open / close and rotation status in various devices. This IC includes 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.
