ON Semiconductor Corporation agreed to sell its Ignition IGBT business in order to settle charges that its proposed $2.4 billion acquisition of Fairchild Semiconductor International, Inc. would likely substantially lessen competition in the worldwide market for Ignition IGBTs, resulting in higher prices and reduced innovation. Ignition IGBTs are semiconductors that function as solid-state electronic switches in the ignition systems of automotive internal combustion engines. The order preserves competition by requiring ON to divest its Ignition IGBT business to Chicago-based manufacturer Littelfuse, Inc. The divestiture includes design files and intellectual property that Littelfuse needs to manufacture ON’s Ignition IGBTs. ON must also facilitate the transfer of its customer relationships to Littelfuse, and supply Ignition IGBTs for Littlefuse to sell to customers while Littelfuse sets up its manufacturing operations.
