Linear LED Driver, 24-Channel, Bus Controlled LV52511MNZ Overview The LV52511MN is a serial bus controlled linear low side driver for LEDs (or other loads). The 24 channels are grouped in 3 color blocks www.onsemi.com (RGB) of 8 channels each. The ON-time for each channel can be programmed by an 8bit register. The reference current is programmed by a single resistor, a 5bit register defines the current for each color block as a fraction (3 to 100%) of the reference current to adjust for color temperature. Systems parameters can be programmed via 2 wire serial bus, or 3 148 2 wire SPI bus with EN, and I C serial bus format (Hs-mode).
