LV5207LP
For Cellular Phone
LED Driver
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

PVCC
External tricolor LED control pin.
VDD
When serial RSW, GSW, and BSW are set to ON,
setting the application voltage H causes tricolor LED to
go ON. When the application voltage set to L, tricolor
LED goes OFF. Note that if the setial setting STLEN is
set to ignore SCTL, tricolor LED goes ON regardless of
the state of SCTL.

RT
Reference current setting resistor connection pin.
By connecting the external resistor between this pin and
PVCC
GND, the reference current is generated. The pin
voltage is about 1V. Change of this current value
enebles change of the oscillation frequency and LED
driver current value.

Feedback is applied so that the current flow through the

output transistor becomes equal to the set current
value. Each driver output current value can be adjusted
independently with the 0.6 step from about 0.8mA to
19.4mA through serial setting. These pins are turned
ON only when the SCTL pin is set high or the serial
SCTEN pin is set to ignore SCTL. These pins function
as the charge pump switchover detection pin from ×1
mode to ×1.5 mode. Pin voltage of about 0.5V or lower
switches the charge pump to ×1.5 mode.

When MAX current is set, the pin voltage of about
0.35V or lower switches the charge pump to ×1.5 mode.
If three MLED are used, MLED4 can be independently
set ON/OFF with serial setting. Note that MLED4 :ON is
active only with MSW:ON. Connect MLED4 pin to VBAT

I2C bus transmission method
Start and stop conditions
In the I2C bus, SDA must basically be kept in the constant state while SCL is "H" as shown below during data
transfer.
SCL
SDA
ts2
th2
When data transfer is not made, both SCL and SDA are in the "H" state.
When SCL = SDA = "H", change of SDA from "H" to "L" enables the start conditions to start access.
When SCL is "H", change of SDA from "L" to "H" enables the stop conditions to stop access.
Start condition
Stop condition

SDA
Data transfer and acknowledgement response
After establishment of start conditions, data transfer is made by one byte (8 bits).
Data transfer enables continuous transfer of any number of bytes.
Each time the 8-bit data is transferred, the ACK signal is sent from the receive side to the send side.
The ACK signal is issued when SDA on the send side is released and SDA on the receive side is set "L" immediately
after fall of the clock pulse at the SCL eighth bit of data transfer to "L".
When the next 1-byte transfer is left in the receive state after transmission of the ACK signal from the receive side,
the receive side releases SDA at fall of the SCL ninth clock.
In the I2C bus, there is no CE signal. Instead, 7-bit slave address is assigned to each device and the first byte of
transfer is assigned to the command (R/W) representing the 7-bit slave address and subsequent transfer direction.
Note that only WRITE is valid in LV5207LP.
The 7-bit address is transferred sequentially from MSB and the eight bit is "L" representing WRITE.
In LV5207LP, the slave address is specified as (1110101).
