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)/I
C 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 addresssetting pins.

• 9-channel output constant-current LED driver/open drain output LED driver (selected by using an external pin)
• Luminance adjustment using internal PWM control (256 steps)
• Fade-in/fade-out function (PWM control priority), supporting synchronous connection
• Selection of 3-wire/I
• C serial bus control signals enabled (switching using an external pin)
• Low current consumption
• Output malfunction protection circuits (thermal protection function, UVLO detection protection function)
