LV5235V

www.DataSheet.co.kr Ordering number : ENA1941A Bi-CMOS IC LV5235V Overview 18-channel LED Driver The LV5235V is a 18-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 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. Features 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 ou...
