S-57K1 A Datasheet, Specifications, Parts list and Support

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.

Parts List

U(Ux), S and G at the end of the product name of ABLIC Inc. were used to indicate different material specifications as “environmental code”,
however, these have now been unified into “lead-free and halogen-free” and are identical in terms of environmental quality.
Note: Lead-free plating other than 100% Sn is applied to some limited old products, therefore, please contact our sales representatives for details.
These descriptions may be different from the actual product name and parameter.
Please confirm the product name and specifications with the data sheet again.
