Automotive ICs

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

Hall effect ic for automotive

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.
