THL3512
24-channel LED Driver with LVDS Interface
Descriptions
The THL3512 is an 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.
