Overview

The 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 multi-drop connection offers the maximum flexibility for designers to place and connect LED drivers. The simple and one-way communication 金年会官方登录tocol is easily-controlled and requires less CPU resources.
