SAN FRANCISCO/FRANKFURT—Apple Inc. is taking control over the power-management technology at the heart of its iPhones in a $600 million deal with Dialog Semiconductor that also secures the German-listed company’s role as a supplier to the U.S. tech giant.
The agreement to license technology and take on people from the Anglo-German chip designer is not only unusual, but also the largest of its kind by Apple, whose last sizeable acquisition was the $350 million purchase of Face ID creator PrimeSense in 2013.
