LV5239TA Linear LED Driver, 24-Channel, Bus Controlled Overview The LV5239TA is a serial bus controlled linear low side driver for LEDs (or other loads). The 24 channels are grouped in 3 color blocks (RGB) of 8 channels each. The ON-time for each channel can be programmed by an 8 bit register. The reference current is programmed by a single resistor, a 3 bit register defines the current for each color block as a fraction (20 to 100%) of the reference current to adjust for color temperature.
