THL3502 is a LED driver with 24 channel open-drain 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.
