Light Management Units description

The standard backlight and keypad lighting functions are enabled in a flexible way by either a charge pump or an inductive step-up converter. The ICs come with a sophisticated, autonomous pattern generator which produces cool event and fun light patterns. They also support new features such as ambient light sensing and daylight sensing.
Some of the products offer light-to-audio synchronization for use in phones with a media playing capability. The lighting management product portfolio meets the space, feature and cost requirements of all phones from entry-level products up to high-end smartphones.
