LV5231CS

Overview

The LV5231CS is 16ch LED driver IC for the cell phones with built-in charge pump circuit.

Features

• LED driver ×16 (3-color ×2, MAIN, Flash) and on-chip switching regulator control circuit.

• Each LED driver current level can be adjusted independently over the serial bus.

• Support strobe mode of LED for flash.

• Ring tone signal and 3-color LEDs synchronization function.

• Gradation function (3-color LEDs)

• Miniature package

Function

• PWM switching regulator control circuit

Built-in Triangular wave oscillator, Standard voltage, PWM comparator, Driver, DTC and short-circuit protection

circuit.

The output interception circuit at the overload is a timer latch method.

• LED driver

LED driver for the main liquid crystal backlight ×6

LED current can be switched indecently in 6-bit units (0.4 to 25.6mA)

External current value control pin is provided.

As for MLED6, a possible independent control (0.6 to 19.2mA)

3-colorLEDs driver ×2

LED current can be switched indecently in 5-bit units (0.5 to 16mA)

Ring tone synchronization function (forced activation with SCTL: High)

It corresponds to the information mode. RGBLED1 only, Built-in low current consumption internal oscillator

Gradation function

Twice current mode (1 to 32mA) RGBLED2 only

LED driver for flash ×4

LED current can be switched indecently in 4-bit units (2 to 32mA)

At the strobe mode (6 to 96mA) (FCTL: High)

Flash mode 1sec limiter (It is an automatic migration in a normal mode after about 1sec at continuousness High of

FCTL).

As for FLED3 and FLED4, a possible independent control.

2) I²C bus transfer method

Start and stop conditions

During data transfer operation using the I²C bus, SDA must basically be kept in constant state while SCL is “H” as

shown below.

SCL

SDA

ts2

th2

When data is not being transferred, both SCL and SDA are set in the “H” state.

When SCL=SDA is “H,” the start condition is established when SDA is changed from “H” to “L,” and access is started.

When SCL is “H,” the stop condition is established when SDA is changed from “L” to “H,” and access is ended.

STOP condition

START condition

SCL

SDA

ts3

th1

Data transfer and acknowledgement response

After the start condition has been established, the data is transferred one byte (8 bits) at a time.

Any number of bytes of data can be transferred continuously.

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 to “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 sending the ACK signal from the receive side, the receive

side releases SDA at the fall of the SCL ninth clock.

In the I²C bus, there is no CE signal. In its place, a 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 address and subsequent transfer direction. Note that

only write is valid in this IC. The 7-bit address is transferred sequentially starting with MSB, and the eighth bit is set to

“L” which indicates a write.

In the LV5231CS the slave address is specified as "1110100"

Precautions for serial transmission and usage note

* The switching regulator must start when it is LED driver OFF.

* Set the setting of the gradation in the state of gradation OFF.

* Set the setting of the MLED4, MLED5 and MLED6 in the state of MSW ON.

• When LED pin unused

Connect the LED driver pin with V

or GND when you do not connect LED with the LED pin.

BAT

• Information LED lighting

Impress the V

voltage when information LED lights because the oscillator for information LED lighting is

voltage.

DD

operated by the V

DD

• FLED use time

Using FLED (An independent mode is excluded) must use FLED1.

The use of FLED2, 3, and 4 is prohibited by FLED1:OFF.
