The S-57K1 A Series, developed by CMOS technology, is a high-accuracy Hall IC that operates with high temperature and

high-withstand voltage.

The output voltage changes when the S-57K1 A Series detects the intensity level of magnetic flux density and a polarity

change. Using the S-57K1 A Series with a magnet makes it possible to detect the rotation status in various devices.

The S-57K1 A Series 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, the S-57K1 A 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
