BCT3253

Ver 1.0 BCT3253 3ch Current Sink RGB LED driver for illumination Introduction The BCT3253 is a 3 channel current sink RGB LED driver. Each channel can be independent programmed by I2C interface and can be configured up to 256 constant current level. By synchronous clock function, combined operation of three channels is possible. It can be used to make amazing lighting effects of over 67million colors for portable devices. With the build-in internal RAMs, the RGB lighting effects can be running independently, which can save the system (CPU/MCU/AP) resources. Less than 2 uA shut down current effective extend battery usage time. BCT3253 is a lead-free environmental protection product, and the temperature range is -40 ℃ to + 85 ℃. It offers in tiny 12Pin 1.6 x 1.2 WCSP package, with the thickness of 0.65 mm.
