LED DriverRGB LED driversTHL3512
Overview
The THL3512 is an LED driver with 24 channel opendrain 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.
