Omnipolar/Unipolar Detection Type Hall Effect Switch IC S-5712A/B/C Series

The S-5712A/B/C Series, developed by CMOS technology, is a high-accuracy Hall effect switch IC that operates at a low voltage and low current consumption. The output voltage changes when the S-5712A/B/C Series detects the intensity level of magnetic flux density. Using the S-5712A/B/C Series with a magnet makes it possible to detect the open/close in various devices. High-density mounting is possible by using the small SOT-23-3 or the super-small SNT-4A package. Due to its low voltage operation and low current consumption, the S-5712A/B/C Series is suitable for battery-operated portable devices. Also due to its high-accuracy magnetic characteristics, the S-5712A/B/C 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.
