HIGH-WITHSTAND VOLTAGE
HIGH-SPEED UNIPOLAR DETECTION TYPE HALL IC
Rev.1.0_00
© Seiko Instruments Inc., 2014
The S-5731 Series, developed by CMOS technology, is a unipolar detection type Hall IC with high-withstand voltage, highspeed detection and high-accuracy magnetic characteristics.
The output voltage changes when the S-5731 Series detects the intensity level of magnetic flux density. Using the S-5731
Series with a magnet makes it possible to detect the open / close and rotation status in various devices.
The S-5731 Series 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, the S-5731 Series can make operation's dispersion in the system
combined with magnet smaller.
Caution
This product is intended to use in general electronic devices such as consumer electronics, office
equipment, and communications devices. Before using the product in medical equipment or automobile
equipment including car audio, keyless entry and engine control unit, contact to SII is indispensable.
