THL3504 24-channel Constant Current LED Driver with LVDS Interface DESCRIPTIONS 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 os cillat or an d P W M co nt ro l l er 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. 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.
