3-Channel LED Driver for Cell Phones

Ordering number : ENA0183A
LV5213LP
Bi-CMOS LSI
3ch LED Driver
http://onsemi.com
Overview
This LV5213LP is LED driver for cell phones. Each LED driver gets a constant current controlled. The brilliance
control becomes possible by changing the current value that flows to LED by the serial bus control.
LV5213LP can achieve various effects of the illumination of a full-color LED display.
Functions
• Three color LED driver circuits.
• The LED current can be switched independently in 5-bit units (0 to 5mA).
• 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 serial bus.
• Miniature package.
• Thermal shutdown circuit.

After 16 clock cycles have been input with CS at the high level, SDATA is acquired on the fall of CS.
Note: SDATA will not be acquired if 15 or fewer clock cycles were input during the CS high-level period. If 17 or more
clock cycles are input, the SDATA for the first 16 cycles are acquired and the SDATA following those 16 cycles is
ignored.
Power Supply Application
1. Either bring up VCC and VDD at the same time, or bring up VCC first then VDD.
2. Then, set the serial data. (After the serial data has been set, a period of about 2µs is required as the startup time for
the IC internal circuits.)
3. Finally, clear the STBY pin states.
