Overview
This LV5217GP is 3-channel LED driver for cell phones. Each LED driver current can be adjusted by I2C bus. LV5217GP can perform various illumination effects with a full-color LED display.
Features
? Three color LED driver circuits. ? The LED current can be switched independently in 7-bit units (0.31 to 25.48mA). ? Independent on/off control of the three LED drivers (independent control of the 3 RGB colors). ? Each LED drive current level can be adjusted independently over the I2C bus. ? Miniature package. ? Thermal shutdown circuit.

LEDON
LV5217GP
Description
Control inputs for the three external colored LEDs. When an RSW, GSW, or BSW bit in the serial data is set to 1, the corresponding LED will be on when the voltage applied to the corresponding pin is high, and off when the voltage applied is low.
