The KTD2061/58/59/60 are fully programmable current regulators for up to 12 RGB LED modules (36 LEDs total) for industrial applications. The devices 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 I2C bus, the KTD2061/58/59/60 have different slave addresses.
36 independent fade-up/down engines are integrated for independent ramping of each LED’s current during 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 ultrasmooth 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 KTD2061/58/59/60 are packaged in RoHS and Green compliant 3mm x 3mm UQFN packages with 0.58mm maximum height.
Automotive grade (-40°C to 125°C) version of this product: KTD2061Q/58Q/59Q/60Q.
