The S-5724 Series, developed by CMOS technology, is a high-accuracy Hall effect latch IC that operates at a low voltage with a highsensitivity,a high-speed detection and low current consumption.
The output voltage changes when the S-5724 Series detects the intensity level of flux density and a polarity change. Using the S-5724 Series with a magnet makes it possible to detect the rotation state in various devices.
High-density mounting is possible by using the small SOT-23-3 or the super-small SNT-4A packages.
Due to its high-accuracy magnetic characteristics, the S-5724 Series can make operation’ s dispersion in the system combined with magnet smaller.

Caution: This product is intended to use in general electronic devices such as consumer electronics, office equipment, and communications devices. Before using the product in medical equipment or automobile equipment including car audio, keyless entry and engine control unit, it is imperative to contact our sales representatives.
