Bi-CMOS IC
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 … 0.96m A to 30.7m A (RGB drive) Constant current (IO max=50m A) for full-color LEDs × 18 channels
- In the open drain mode (OUTSCT: M), high current drive (IO max=100m A) × 18 channels
- In the constant-current mode (OUTSCT: H) Only RGB6 is open drain (IO max=100m A)
- 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 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)
