LED DriverDigital SignageTHL3504
Overview
The THL3504 is a LED driver with 24 channel constant current outputs. 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. 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.
