Bi-CMOS IC
9-channel LED Driver
http://onsemi.com
Overview
The LV5234V is a 9-channel LED driver IC that is capable of switching between constant-current output and open
drain output. It enables 3-wire serial bus control (address designation)/I2C serial bus control to be set arbitrarily using
an external pin. Also possible are 9-channel LED ON/OFF control and the setting of the PWM luminance in 256 steps.
The device also has a built-in fade-in/fade-out function. Up to 32 driver ICs can be connected using the slave address
setting pins.
Function
• 9-channel output constant-current LED driver/open drain output LED driver (selected by using an external pin)
Supports separate ON/OFF setting for each LED output, high withstand voltage (VOUT<42V)
• In the constant-current mode (OUTSCT: L), the reference current is set by the value of resistor connected
to the external pin (RT1).
Built-in D/A (5 bits) for switching current level … 0.96mA to 30.7mA (RGB drive)
Constant current (IO max=50mA) for full-color LEDs × 9 channels
• In the open drain mode (OUTSCT: H), high current drive (IO max=100mA) × 9 channels
• Luminance adjustment using internal PWM control (256 steps)
• 8-bit PWM luminance dimming (0% to 99.6%)
• 3-phase PWM
• Fade-in/fade-out function (PWM control priority), supporting synchronous connection
• Supports separate fade ON/OFF for each LED output (fade time common for all channels)
• Interrupt control possible for fade function
• Selection of 3-wire/I2C serial bus control signals enabled (switching using an external pin)
Slave addressing (5 bits, connection of up to 32 driver ICs possible)
• Low current consumption
• Output malfunction protection circuits (thermal protection function, UVLO detection protection function)

Data length:

Clock frequency: 5 MHz or less
When 24 SCLK clock signals have been input during the high period of SDEN, the SDATA is taken in at the rising edge of
SCLK.
Note: If the number of SCLK clock signals during the high period of SDEN is 23 or less, SDATA is not taken in. If it is 25 or
more, the register address is automatically incremented every time 1 byte is taken in.
The slave address is assigned by the first byte, and the register address on the serial map is specified by the next byte.
The third byte transfers the data to the address specified by the register address that was written by the second byte and if the
data subsequently continues even after this, the register address is automatically incremented for the fourth and subsequent
bytes. As a result, it is possible to send the data continuously from the specified addresses. Data of less than one byte is ignored.
However, when the address reaches 15h, in the next byte to be transferred becomes 00h.

I C 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.

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.
