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.

LV5239TA Features

* LED supply from 3 V to TBDV with transient tolerance up to 42 V.

* System supply from 3 V to 12 V with transient tolerance up to 13.6 V.

* Up to 100 mA resistor defined maximum current for all channels.

* 3 bit individually adjustable current for each color group RGB.

* 8 bit l
