Product Name
Silicon Monolithic Integrated Circuit
RGB Illumination LED Driver for mobile phone
Type
BD2812GU
Features
RGB LED driver
A slope control function is incorporated
Slope control can be implemented using the DC current.
Two modes “continuous illumination mode” and “illumination single cycle mode” are supported.
Independent external ON/OFF synchronizing terminals (of dual drivers) are provided.
Low consumption operation is possible by the sleep operation mode function.
Charge pump system DC/DC built-in.
