LV5207LP
Bi-CMOS IC
LED Driver for Cellular Phone
http://onsemi.com
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
