SANYO LV5217GP_10

Ordering number : ENA0833A
LV5217GP
Bi-CMOS IC
3ch LED Driver
Overview
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.

Control inputs for the three external colored LEDs.
VCC
When an RSW, GSW, or BSW bit in the serial data

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.

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.

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.”
