Rev.2.1_00 BIPOLAR DETECTION TYPE HALL IC WITH POWER-DOWN FUNCTION S-5721A/5722A Series The S-5721A/5722A Series, developed using CMOS technology, is a bipolar detection type Hall IC with a high-sensitivity that operates on a low current. The output voltage changes when the S-5721A/5722A Series detects the intensity level of flux density and a polarity change. Using the S5721A/5722A Series with a magnet makes it possible to detect rotation in various devices. High-density mounting is possible.
