Our LED controllers enable core functions in some of today’s most ubiquitous devices and applications. In cellular handsets, LED blinkers and dimmers control keypad, fun lighting and status LEDs. LED controller ICs can also be used for more advanced status or illumination control while off-loading host processors in LCD displays. These LED controllers work with I2C interfaces for applications such as: RGB or RGBA LED drivers, LED status information, LED displays, LCD backlights, keypad backlights for cellular phones or handheld devices.
