The S-57P1 S Series, developed by CMOS technology, is a high-accuracy Hall effect latch IC that operates with high temperature and high-withstand voltage.
The output voltage changes when the S-57P1 S Series detects the intensity level of magnetic flux density and a polarity change. Using the S-57P1 S Series with a magnet makes it possible to detect the rotation status in various devices.
The S-57P1 S Series includes a reverse voltage protection circuit and 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, the S-57P1 S Series can make operation’s dispersion in the system combined with magnet smaller.
Caution : This product can be used in vehicle equipment and in-vehicle equipment. Before using the product in the purpose, contact to SII is indispensable.
