The S-57K1 A 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-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 state 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.
