LV5207LP

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 go es 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

Block Diagram and Sample Application Circuit

* The value of the external capacitor connected to the charge pump circuit can be reduced depending on the load current.

The min imum rating of the Load cur rent doesn't increase even if 2.2μF or more capacitor is used.

Pin Functions

Pin No. Pin name Pin Description Equivalent Circuit

1 TEST Test signal input pin.

Be sure to connect the pin to GND.

2 SCTL External tricolor LED control pin.

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.

3 RT Reference current setting resistor connection pin.

By connecting the external resistor between this pin and

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.

Tricolor LED driver pins.

Feedback is applied so that the current flow through the

output transisto r be comes 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 ch arge pum p 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.

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.

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.

Data transfer and acknowledgem ent response

After establishment of start conditio ns, data tr ansfer is made by one byte (8 bits).

Data transfer enables continuo us 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).
