Kinetic Technologies KTD2061/KTD2058 36-Channel RGB LED Drivers

Kinetic Technologies KTD2061/KT2058 36-Channel RGB LED Drivers are fully programmable current regulators for up to 12 RGB LED modules. The driver is 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 red-green-blue module. Kinetic KTD2061/KTD2058 integrates a hardware fade engine per channel, which reduces the amount of software commands traditionally required to implement a lighting pattern. BrightExtend™ technology enables battery operation by decreasing dropout when the input voltage is too low for the forward voltage of the LEDs.
