LV5105FN
Bi-CMOS IC
For cell phone system
Power supply
Overview
The LV5105FN is a power supply for a cell phone system that integrates four series regulators, LED driver (with 5V
output) on a single chip.
Functions
• REG×4 (CMOS output)
• DET circuit (one for REG1, one for VBAT (with reset output)
• Thermal shutdown circuit (150°C)
• Three-color LED driver (charge pump 5V output incorporated)
• FRONT LED driver
• Mic bias output
Features
• Low power consumption
• Built-in charge pump circuit
• Built-in 3-color LED drive circuit
4μA when REG4 and VBATDET operate
30μA when REG1, REG2, REG3, and REG4 + DET1 and VBATDET operate
VBAT : 3.2V to 4.5V, 5V constant output with a load of 80mA
Three independent colors, 128-step PWM intensity control

"SDATA" is taken in at fall of "SDEN" when "SCLK" of 24 clock is entered during H period of "SDEN."
(Note) "SDATA" is not taken in when "SCLK" is 23 clock or less during H period of "SDEN."
When "SCLOCK" exceeds 25 clock, "SDATA" is taken in at the 24th clock, and subsequent "SDATA" is
ignored.
