The device s are ideally powered from a supply rail in the 3V to 5V nominal range. Three 4 -wire buses are multiplexed to reduce the pin-count and PCB traces to the LEDs. The I2C control interface is used to set the LED color palette and then dynamically select the on/off status and color of each RGB module. For applications requiring more RGBs on one I 2C bus, t he KTD2061Q/58Q/59Q/60Q have different slave addresses. 36 independent fade-up/down engines are integrated for independent ramping of each LED’s current duri ng on/off, brightness, and color transitions without software burden. The exponential current ramps provide visually pleasing fades with eight I2C programmable fade-rate settings. 3072-step fade resolution ensures ultra - smooth visual effects. BrightExtend™ optionally reduces dropout when the input voltage is too low for the forward voltage of the LEDs, enabling battery -powered applications . Programmable CoolExtend™ prevents excessive heat by regulating die temperature when the input voltage, current settings, and/or ambient temperature are high. The KTD2061Q/58Q/59Q/60Q are packaged in RoHS and Green compliant 3mm x 3mm UQFN packages with 0.60mm maximum height.
