125°C OPERATION HIGH-SPEED
UNIPOLAR DETECTION TYPE HALL IC
Rev.3.0_00
This IC, 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 this IC detects the intensity level of flux density. Using this IC with a magnet makes it
possible to detect the open / close and rotation state in various devices. High-density mounting is possible by using the
small SOT-23-3 package. Due to its high-accuracy magnetic characteristics, this IC can make operation’s dispersion in the
system combined with magnet smaller.
SII Semiconductor Corporation offers a "magnetism simulation service" that provides the ideal combination of magnets and
our Hall ICs for customer systems. Our magnetism simulation service will reduce prototype production, development period
and development costs. In addition, it will contribute to optimization of parts to realize high cost performance.
For more information regarding our magnetism simulation service, contact our sales office.
