LV5236V
Bi-CMOS IC
24-channel LED Driver
Overview
The LV5236V is a 24-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 24-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.
Features
24-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 × 24 channels
In the open drain mode (OUTSCT: M), high current drive (IO max=100mA) × 24 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%)
8-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)
