For Automotive 150°C Operation High-Withstand Voltage High-Speed Bipolar Hall Effect Latch IC S-57P1 S Series

The S-57P1 S 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-57P1 S Series detects the intensity level of magnetic flux density and a polarity change. Using the S-57P1 S Series with a magnet makes it possible to detect the rotation status in various devices.

Magnetic simulation service
ABLIC Inc. offers a “magnetic simulation service” that provides the ideal combination of magnets and our magnetic sensor ICs for customer systems.

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.
