概觀
IS31FL3194 is a 3-channel 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 (1.0mm×1.6mm)
package. It operates from 2.7V to 5.5V over the
temperature range of -40°C to +85°C.
