LED Control IC W2RG012RN 17
Drive Output Group
Adjoining drive output terminals (OUT0R - 7B) have different change timings. This difference is designed to reduce noise caused by the simulta-
neous change of drive output. There are 4 change timings, by which drive outputs are grouped as follows:
Note: *This does not apply when the division mode is set as 16x8 configuration, in which case the following operations are executed:
OUT5G - 6G: Not used.
OUT6B - OUT7B: Functions as OUTS4 - 7
Synchronous Control Output
Synchronous control output terminal (OUTDC) outputs control signals synchronized with lighting switch. These signals are used to drive external
circuits at lighting switch.
■ Power-saving Control
Power saving data is set, via communications as 100%, 75%, 50% or 25%. Current or duty ratio control is used as control method. Power saving
data can be set separately via either of these methods.
Current Control
Output currents are changed collectively according to a designated ratio to a current set with current setting terminal REXTR/REXTG/REXTB.
Note: The hue of a full-color LED in normal operation may be different from that in power-saving operation, due to differences in current charac-
teristics among R/G/B.
Duty Ratio Control
Output duty ratios are changed collectively according to a designated ratio to a duty ratio designated to a particular gradation.
