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.

Systems parameters can be programmed via 2 wire serial bus, or 3 wire SPI bus

with EN.
