LV5219LG
Bi-CMOS IC
For cell phone
LED driver
Overview
The LV5219LG is an LED driver IC for cellular phones. It incorporates 17 LED drivers (main, sub, tricolor × 2, and
flash) and a switching regulator circuit and supports the step-up through mode. Each LED current level can be adjusted
over the I²C serial bus. The LED driver IC also has functions to synchronize a ringing tone with a tricolor LED and to
automatically control the brightness of white LEDs by brightness sensor.
