This IC, developed by CMOS technology, is a high-accuracy Hall effect latch IC that operates with high temperature and high-withstand voltage.
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.

Magnetic simulation service
ABLIC Inc. offers a “magnetic simulation service” that provides the ideal combination of magnets and our Hall effect ICs for customer systems. Our magnetic simulation service will reduce prototype production, development period and development costs. In addition, it will contribute to optimization of parts to realize high cost performance.

Features

  • Uses a thin (t0.80 mm max.) TSOT-23-3S or ultra-thin (t0.50 mm max.) HSNT-6(2025) package, allowing for device miniaturization
  • Contributes to reduction of mechanism operation dispersion with high-accuracy magnetic characteristics (Typ. value ± 1.0 mT) (Refer to “Magnetic Characteristics” in the datasheet for details.)
  • Contributes to device safe design with a built-in output current limit circuit
