BCT3299
The BCT3299 is a LED driver with independent 16 output channels, and the output current of each channel can be programmed to achieve 256 level, with maximum up to 30 mA.
The device is equipped with an internal program memory, which allows the operation without processor control. Each channel is independently programmed to on, off, gradually light up or down over time. In audio mode, the brightness of each channel can be proportional to the strength of the audio signal, also there will be the PWM output which sync to the audio signal. BCT3299 is designed to produce versatile lighting effects for portable devices.
Less than 2uA chip off current effective extend battery usage time, BCT3299 is lead-free environmental protection products, and the temperature range is -40 ℃ to + 85 ℃. It has QFN-24 (4 x 4 mm) package, with the thickness of 0.75 mm.
