High-speed Bipolar Hall Effect Latch IC S-57M1 Series

This IC, developed by CMOS technology, is a high-accuracy Hall IC that operates with a high-sensitivity, a high-speed detection and low current consumption.
The output voltage level changes when this IC detects the intensity level of magnetic flux density and a polarity change.
Using this IC with a magnet makes it possible to detect the rotation status 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 high-accuracy magnetic characteristics, this IC 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.
