Bi-CMOS IC

For Cellular Phone

LV5207LP

LED Driver

Overview

The LV5207LP is an LED driver IC for cellular phones. It incorporates 7 LED drivers (tricolor and main) and a charge

pump circuit. The LV5207LP allows each LED current value to be regulated by a serial bus and has a function to

synchronize a ringtone melody.

Functions

• Charge pump

×1/×1.5 mode switchover

The mode switches (step-up only and no step down) when the LED pin voltage goes down. When VBAT is 4.6V and

above, this IC becomes only ×1 mode.

• LED drivers

Main LCD backlight LED×4 (LED current 5-bit changeover 0.8mA to 19.4mA)

Tricolor LED driver×1 (LED current 5-bit changeover 0.8mA to 19.4mA
