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)
