Overview
Bi-CMOS IC
For Cell Phones
3ch LED Driver
This LV5217GP is 3-channel LED driver for cell phones. Each LED driver current can be adjusted by I2C bus. LV5217GP can perform various illumination effects with a full-color LED display.
Features
* Three color LED driver circuits. * The LED current can be switched independently in 7-bit units (0.31 to 25.48mA). * 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 I2C bus. * Miniature package. * Thermal shutdown circuit.

I2C bus transmission method START condition and STOP condition When transferring data over an I2C bus, SDA must basically be held in certain states while SCL is High, as shown in the figure below.
SCL
SDA ts2 th2
Both SCL and SDA are high when not performing data transfer. When both SCL and SDA are high, changing SDA from high to low generates the START condition and starts access. Changing SDA from low to high while SCL is high generates the STOP condition and ends access.
Start condition
Stop condition
SCL
SDA th1 th3
Data transfer and confirmation response After the START condition is generated, data is transferred one byte (8 bits) at a time. Data can be transferred continuously for any number of bytes. The ACK signal is sent from the receiving to the transmitting side each time 8 bits of data are transferred. The transmitting side releases the SDA line immediately after the SCL clock pulse corresponding to the 8th data transfer bit as it falls to Low, and the receiving side then sends the ACK signal by setting SDA Low. After the receiving side sends the ACK signal, if the next byte transfer is still in receive mode, the receiving side releases the SDA line at the falling edge of the 9th SCL clock. The I2C bus does not have a CE signal, so instead a 7-bit slave address is assigned to each device. The first byte of each transfer is assigned to this 7-bit slave address and a command (R/W) indicating the transfer direction of the following data. Note that only Write mode is valid for this IC. The 7-bit address is transferred in order from the MSB, and the 8th bit is Low to indicate Write mode. The LV5217GP slave address is prescribed as "1110101."
