HIGH-SPEED BIPOLAR HALL EFFECT LATCH
The S-57M1 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-57M1 Series detects the intensity level of magnetic flux density and a polarity
change. Using the S-57M1 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 package.
Due to its high-accuracy magnetic characteristics, the S-57M1 Series can make operation’s dispersion in the system
combined with magnet smaller.
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 Semiconductor Corporation is indispensable.
