.Data Sheet.co.kr Ordering number : ENA1936A Bi-CMOS IC Overview 9-channel LED Driver 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. Features - 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 … 0.96m A to 30.7m A (RGB drive) Constant current (IO max=50m A) for full-color LEDs × 9 channels - In the open drain mode (OUTSCT: H), high current drive (IO max=100m A) × 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 mon 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) Any and all SANYO Semiconductor Co.,Ltd. products described or contained herein are, with regard to "standard application", intended for the use as general electronics equipment.
