Product Description
Product Overview
The SS351AT, SS451A, and SS551AT are omnipolar digital Hall-effect sensor ICs that turn on (output low) with either a North or South magnetic pole and turn off (output high) when the magnetic field is removed. These devices are sensitive to electrostatic discharge (ESD) and require standard ESD precautions during handling. Soldering instructions include limiting exposure to high temperatures and specific reflow/wave solder parameters to prevent product damage.
