The S-5725 Series, developed by CMOS technology, is a high-accuracy Hall IC that operates with a high-sensitivity, a high-
speed detection and low current consumption.
The output voltage changes when the S-5725 Series detects the intensity level of magnetic flux density and a polarity
change. Using the S-5725 Series with a magnet makes it possible to detect the rotation status 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-5725 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, contact to SII is
indispensable.
