125°C Operation, High-Withstand Voltage, High-Speed, Bipolar Hall Effect Latch IC S-576B B Series

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.

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
