High-Withstand Voltage High-Speed Unipolar Detection Type Hall Effect Switch IC S-5731 Series

The S-5731 Series, developed by CMOS technology, is a unipolar detection type Hall effect switch 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.

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.
