LV5235V

Overview

The LV5235V is a 18-channel LED driver IC that is capable of switching between constant-current output and open

an external pin. Also possible are 18-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

• 18-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

× 18 channels

• In the open drain mode (OUTSCT: M), high current drive

(IO max=100mA) × 18 channels

• In the constant-current mode (OUTSCT: H)

Only RGB6 is open drain (IO max=100mA)

• Luminance adjustment using internal PWM control (256 steps)

• 8-bit PWM luminance dimming (0% to 99.6%)

• 6-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

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)
