THL3504

24-channel Constant Current LED Driver with LVDS Interface

DESCRIPTIONS

FEATURES

The THL3504 is an LED driver with 24 channel constant

current sink outputs. The constant current values for

three output groups are determined by external resistors.

The embedded oscillator and PWM controller

individually generates 256-step brightness set by the

dedicated registers for each channel.

The serial interface of 2-pair LVDS lines (clock and

data) features high-level noise tolerance, high-speed, and

long-distance transmission.

< Driver part >

- Constant Current Output: 24 channels

- Output Sink Current: up to 40mA/ch

- Output voltage: up to 40V

- Individual Brightness Control: 256 steps

- Group Brightness Control: 64 steps

- Output disable/enable

< Serial interface part >

The LVDS allowing cascaded and multidrop connection

offers the maximum flexibility for designers to place and

connect LED drivers.

The simple and one-way communication protocol is

easily-controlled and requires less CPU resources.

- 2-pair Serial LVDS Input or 3-wire Serial CMOS Input

up to 10Mbps

- Bridge Function Converting 3-wire Serial

CMOS Input to 2-pair Serial LVDS Output

- Repeater function of 2-pair Serial LVDS Input / Output

with Waveform and Timing Correction

- Device Address Selection up to 62 addresses

- General call to all devices
