概觀

IS31FL3194 is a 3-channel fun LED driver which features two-dimensional auto breathing mode. It has Pattern Mode and Current Level Mode for RGB lighting effects. The maximum output current can be adjusted in 4 levels (40mA Max.). In Current Level Mode, the current level of each output can be independently programmed and controlled in 256 steps to simplify color mixing. In Pattern Mode, the timing characteristics for output current - current rising(T1), holding(T2), falling(T3) and off time(TS, TP, T4), can be adjusted individually so that each output can independently maintain a pre-established pattern achieving mixing color breathing or a single color breathing without requiring any additional interface activity, thus saving valuable system resources. IS31FL3194 is available in WCSP-8 package. It operates from 2.7V to 5.5V over the temperature range of -40°C to +85°C.
