FxLED Drivers

Lumissil FxLED Drivers are high-performance matrix, multichannel, and RGB LED drivers featuring pre-programmed animation and color-effect lighting functions. These functions are accessed via an I2C-compatible interface. The FxLED drivers offer system designers a wide range of options for bringing eye-catching color functionality to consumer electronics. These pre-programmed functions reduce microcontroller demand, resulting in enhanced performance and low power consumption.  Lumissil FxLED Drivers are ideal for intelligent display applications, including mobile phones, white goods, toys, and personal electronics. The series is also used in automotive applications, including dashboards and decorative displays. These devices are offered in a variety of package options for design flexibility, including TQFN, DFN, WLCSP, and eTSSOP.
